Abstract

Background: Magnetic resonance imaging (MRI) is the tool commonly used in the diagnosis of meniscal tears. It has been suggested that, for clinically suspected meniscal tears, the adoption of routine MRI before therapeutic arthroscopy will reduce the number and cost of unnecessary invasive procedures.The aim of this study was to document MRI yield in knee injuries clinically suspected as possible meniscal tears in Duhok city Subject and Methods: This cross sectional study was conducted during the period from June to December 2014. A consecutive sampling procedure was used to enroll eighty cases of Knee injuries presenting with clinical features of meniscal tears. All patients underwent MRI examination by 1.5 Tesla machine.Results: The mean age of the patients was 33.5 years. The number of males was 58 (72.5%) with mean age 29.55 years while females constituted 22 (27.5%) with mean age 44years.The results revealed that 64 patients (80%) were affected by tear in the medial meniscus compared to 16 patients (20%) in the lateral meniscus .Isolated anterior horn tear was significantly more common in the lateral meniscus(12.5%) than in the medial meniscus (1.25%) while isolated posterior horn tear was more common in the medial meniscus (66.25%) than the lateral meniscus (7.5%)Conclusions: Meniscal tears were more common in males (~ 3/4th of cases) who presented at a younger age. Medial meniscal tears were four times as common as those affecting the lateral meniscus.

Abstract

The uterine fibroid is most common solid uterine tumour , it is single or multiple benign neoplasm and present in 20-40% of women in productive age. There are several factors that are attributed to underlie the incidence and development of these common tumors, but this further corroborates their relatively unknown etiology. The most likely presentation of fibroids is by their effect on pelvic pressure symptoms or the woman’s menstrual cycle .Adenomyosis of the uterus is benign uterine pathology. It is thought by many to be on the spectrum of endometriosis, with ectopic endometrial glandular tissue in the myometrium. Adenomyosis may present with dysmenorrhea and menorrhagia. Ultrasound and MRI are imaging modalities that may show characteristic findings. Diffusion weighted image in MRI has been applied to evaluate the intracranial lesion ,but technical advancement make it possible to use in extra cranial sites. The aim of this study was to assess the differences, if any, in the apparent diffusion coefficient (ADC) values of adenomyosis and fibroids. Methods and Material Total patient of sample study 56 ,Patients (n= 25) diagnosed by ultrasound as uterine fibroids and (n=31) as adenomyosis, who underwent pelvic MR imaging with DWI, were included in this cross section study. DWI was achieved with using a 1.5 T scanner , different b factors of ( 0, 400, and 600 s/mm) and ADC region of interest(ROI) size were located over an area of Adenomyosis, a fibroid and unaffected normal myometrium all results are correlate with histopathological result which was considered as gold standard diagnostic methods. Results using Student’s t test to compare the ADC values of adenomyosis and fibroids. The standard deviation and the mean of the ADC values were as follows: adenomyosis 0.75 ± 0.30, fibroid 0.63 ± 0.29 and myometrium 1.39 ± 0.36. Statically, there was significant difference between the ADC values of normal myometrium and adenomyosis (p < 0.0001), normal myometrium and fibroids (p < 0.0001), and fibroids and adenomyosis (p < 0.001). Conclusion The present study display that ADC values have the possible to quantitatively and significantly differentiate between Adenomyosis and fibroids.

Abstract

Background and objective: Primary brain lymphoma is an extranodal aggressive intracranial neoplasm of lymphocytic origin originating and confined to the brain parenchyma and meninges. It is rare in immune competent patients, but its incidence is increasing. This retrospective study was conducted to record the MRI features of primary brain lymphoma at the time of diagnosis in immunocompetent patients.Methods: Of the 450 patients diagnosed with the brain tumor during a period of five years from 2008 to 2013, the clinical features and MRI findings of 16 cases of pathologically proven to be non-Hodgkin’s lymphoma were studied. All the patients were tested negative for HIV and there was no history of immune suppression drugs or any other chronic illness. All the patients were examined with MRI observing the tumor location, multifocality, signal intensity in different sequences, enhancement patterns, peritumoral edema, the presence of hemorrhage and calcification.Results: Of the 16 patients, including the monofocal and multifocal cases, 30 lesions exhibited. The mean age at diagnosis was 53 years. Nine patients (56.25%) found to have a multifocal disease. In more than 75% of lesions, MRI was hypo to iso signal on T1 and T2. Mild to moderate perilesional edema, strong contrast enhancement and restricted diffusion were seen in all cases. The hemorrhagic tumor was noticed in four lesions (13.3%). No calcification and no leptomeningeal lesions were noted. The MRI images in post steroid therapy were studied within one month of treatment. Tumour regression was noticed in 21/30 (70%), stable in 3/30 (10%) and progressing in 6/30 (20%). Conclusion: MRI is a reliable imaging technique in the management of patients with primary brain lymphoma. Early accurate diagnosis is crucial to avoid the unnecessary operation and shift patients from extensive surgery to chemoradiotherapy.

Abstract

ABSTRACT: BACKGROUND: Deep white matter ischemia (DWMI) is bilateral patchy or diffuse pattern of ischemia and demyelination in the deep white matter region of the brain. WM lesions (WMLs) increase in frequency with age and are associated with lower cognitive performance. Reported prevalence ranges from 5% to 90%, depending on study design, study population, and rating scales. Although the main pathophysiology is still under investigation, they are attributed to degenerative changes of long penetrating arteries and it has been postulated that chronic vascular diseases of the arteries and arterioles supplying these regions can play a role in the process. Deep white matter ischemia is imaged by using T2 weighted (T2W) sequences in addition to FLAIR sequences. Coronal section is used to enable precise sampling of WMLsOBJECTIVE: To assess 3T MRI vs. 1.5 MRI in evaluating the extent of DWMI.PATIENTS AND METHODS: A cross sectional study was conducted at the MRI unit of the Department of Radiology in Al-Imamain Al-Kadhimain Medical City in Baghdad. Data collection was obtained during the period starting on October 2015– June 2016. The study included 87 patients with the diagnosis of DWMI based on previous MRI data. Patients with initial MRI findings that show no evidence of DWMI as well as patients presented with trauma, migraine, epilepsy, tumor, TB and cerebral venous thrombosis were excluded. Each patient was examined by using 3T MRI, followed by a 1.5 T MRI two days later. The patient images were evaluated for 1.number of lesions, 2.size, 3.volume and 4.intensity of a selected prominent lesion.RESULTS: Of the 87 patients, 51 were male and 36 female. Their mean age was 59.48 ± 10.83 years. In all lobes there is a statistical significance (P < 0.0001) between 3T and 1.5T i.e. 3T platform was able to show a greater number of lesions in comparison with the 1.5T platform. It was seen with high statistic significance (P <0.0001) that one the 3T images, mean intensities, sizes, and volumes were higher across the board. The average additional number of lesions shown by 3T over 1.5T was 9.52 lesions with a standard deviation of 6.50. CONCLUSION: Three tesla MRI is significantly superior than1.5 tesla MRI in the number of detected lesions, determining size of a lesion, detecting lesion volume and intensity ز

Abstract

People may believe that tissue of normal brain and brain with benign tumor have the same statistical descriptive measurements that are significantly different from the of brain with malignant tumor. Thirty brain tumor images were collected from thirty patients with different complains (10 normal brain images, 10 images with benign brain tumor and 10 images with malignant brain tumor). Pixel intensities are significantly different for all three types of images and the F-test was measured and found equal to 25.55 with p-value less than 0.0001. The means of standard deviations and coefficients of variation showed that pixel intensities from normal and benign tumors images are almost have the same behavior whereas they were significantly different from images of malignant brain tumors with F-tests equal to 23.22 and 6.51 respectively with corresponding p-values of 0.00001 and 0.005 respectively.

Abstract

Neck pain and backache shows major problems in the society and a common reason for consulting a physician, a rheumatologist, an orthopedic, a physiotherapist, etc. Evaluate the diagnostic accuracy of both electro diagnostic tests and MRI in patient presented with neck pain and lower back ache as well as demonstrate the disproportion between them and their relation to history and clinical findings in Babylon province. Two hundred fifty subjects of both male and female were involved in this study,100 with neck pain, 50 with back ache and the other 100 as a control group, ranged from 30-60 years, all of them were free from other medical and neurological diseases which could affect peripheral or central nervous system . It was conducted on a comprehensive medical and neurological examination in addition to the overall general physical examination of the cervical spine and lumbar sacral spine examination and electrophysiological study which include both nerve conductive study and EMG as well as MRI were done for all the involved groups study. The electrophysiological test were done at the neurophysiology unit of Merjan Teaching hospital in Babylon City ,during the period April2015 to October 2015. This study revealed that cervical neck pain and back pain is more common in female than male . In neck pain 89 % had positive EMG results and mainly the C5-C6 roots lesion segment. Majority of patients had moderate roots lesions severity (49.75%) while those who had sever degree showed the lowest percentage (12.4%). 94% showed positive MRI, most of patients had bilateral root lesion (49.4%) and in unilateral, the left side is more common (32.6%). In this study females were more prevalent than males in developing neck and back pain and these increases with the age. EMG could be more dependable test than MRI in diagnosis root lesion and determining the chronicity of it in which MRI could not reach it, while NCS has little role in diagnosis these cases, so to give more accurate and imperceptible information in diagnosing root lesion both MRI and electro diagnostic study should be done.

Abstract

The anatomy information that provided by MRI made it an indispensable tool for diagnosis purposes in present. There are three orientations of acquiring the sliced images of brain in MRI, which are: sagittal; coronal and axial. So it is a vital task to find out an effective and adequate technique for processing and segmenting MRI sliced images of the three orientations modalities to detect and extract tumors in these images. In this work, a simple and effective technique that, it adequate to segment sagittal and coronal orientations, is proposed. This technique is one of the enhancement methods that based on the histogram of the image. Besides, morphological operations were proposed to isolate and extract the tumor regions adequately from successive sliced MRI images of brain of a patient suffer from brain tumor, to utilize them later in generating three dimensions image of the extracted tumor. In addition, the location of the tumor was determined and hold completely within the contouring map of the patient’s head for the two adopted orientations. The importance of this work involving that, this process gives the surgeon a better view seen for the tumor from different orientations to enable him to find out an optimal path to reach the tumor with minimum damage of the surrounding tissues. This work was achieved by the aid of Mat Lab programming system.
