ABSTRACT
Introduction: Tumors of nerve sheath, neurofibroma and schwannoma represent 30% of intradural extramedullary tumors. Schwannomas and neurofibromas are histologically composed of Schwann cells. Schwannomas almost always arise from the dorsal sensory roots and form well- encapsulated firm masses that compress adjacent tissue, without invading the involved nerve. Neurofibromas are more complex and are composed of Schwann cells mixed with fibroblast they involve the parent nerve. Meningiomas comprise approximately 25% of primary intraspinal tumors and are second only to nerve sheath tumors in frequency. Spinal cord meningiomas are originate from meningothelial cells near the distal root ganglia. Most menongiomas are intradural extramedullary, only 5% are extradural. Aim of the Study: The aim of this study was to evaluate the role of MRI in diagnosis of intradural extramedullary spinal tumors compared to histopathological findings. Methods: This was a cross sectional study and was conducted in the Department of Radiology and Imaging, Sylhet M.A.G. Osmani Medical College, Sylhet in collaboration with Department of Neurosurgery & Pathology of the same hospital, Sylhet, Bangladesh during the period from September, 2018 to August 2020. Result: In total 35 patients completed the study. In our study we found the Mean ± SD of age was 41.71±13.9 in years. Majority (54%) of our patients presented with spinal tumor were male compared to female (46%).We found schwannoma was diagnosed by (42.9%), meningioma (31.4%), neurofibroma (25.7%) respectively. Neurofibroma & schwannoma showed male predominance with 66.67% & 60% while meningioma showed female predominance with 63.6%. We found majority (55.6%, 60% & 72.7%) of neurofibroma, schwannoma & meningioma was in dorsal region respectively. Conclusion: In our study we found that MRI is a very sensitive and effective imaging procedure of suspected spinal schwannoma tumor of the spinal cord for accurate pre-operative diagnosis and ........

ABSTRACT
Background: All general radiographic images must always display a correct permanent anatomical side marker (ASM). However, literature reports a decline in the use of permanent ASMs in digital radiography (DR). The ASM has been reported as one of the most common sources of error in radiography of which some have resulted in performing wrong-site surgery and treatment. Since the installation of a DR X-ray machine in 2015 at the University Teaching Hospital (UTH) no research or audit has been conducted on this subject. Aim: This study aimed at auditing the use of ASMs in digital radiography (DR) and identifying the barriers to the use of permanent ASMs at the University Teaching Hospital (UTH) of Lusaka, Zambia. Methodology: This study was conducted in two phases. The first phase involved a retrospective auditing of the use of ASMs in DR with a sample of 290 radiographic images. Data were collected using a checklist. The second phase was aimed at identifying the barriers to the use of permanent ASMs and suggestions to overcome them. Data were collected using an online questionnaire. Quantitative data were analysed using descriptive statistics, whilst qualitative data from open-ended questions were analysed using content analysis. Results: In the first phase, all the audited images N=290 (100.0%) had electronic (digital) ASMs and were placed on the correct anatomical side (right or left). However, no image had a permanent ASM. A total of N=45 (18.8%) images had ASMs that obscured the anatomy. In the second phase, a total of N=20 (46.0%) respondents agreed that they do not always use permanent ASMs because of a lack of ASMs, increased workload, and time-consuming. Conclusion: This study revealed the non-use of permanent ASMs by radiographers and radiography students. The purchasing of permanent ASMs and delivery of educational awareness programme is recommended as well as frequent auditing.

ABSTRACT
Renal vein thrombosis (RVT) in the post-partum period is rarely reported. It is majorly a complication of the hypercoagulability associated with both pregnancy and postpartum state. We report the case of a primiparous 19-year-old woman, who presented to the Emergency Department complaining of acute right flank pain. Doppler ultrasonography revealed thrombosis of the right renal vein with extension into the inferior vena cava (IVC). Contrast-enhanced abdominal computerized tomography (CT) confirmed the diagnosis. The outcome was favorable after anticoagulation therapy by Heparin was initiated. Practitioners need to be aware of the diagnosis of RVT. Imaging tests, especially contrast CT scans play a major role in the diagnosis and post-therapeutic assessment.

ABSTRACT
Arachnoid cysts are benign, congenital, space-occupying lesions that are filled with CSF (Cerebrospinal fluid). We report an unusual case of a multi-compartmental arachnoid cyst of 25 years old male who complained of gradually increasing headache. Computed tomography and magnetic resonance imaging revealed a large arachnoid cyst involving the left middle and anterior cranial fossae with sub-falcine extension into the right anterior cranial fossa.

ABSTRACT
Infrared thermal imaging technology has been used in medicine since the 1960s (1) but fell out of favour with the introduction of more sophisticated imaging technologies. Recently, there has been a global resurgence in the utilisation of thermal imaging in many regions of the body (2) (Figure 1A). This has been possible due to improvements in camera capability along with development of advanced computational techniques to assist in reading of images. This report will review the important innovations that have renewed the utilisation of breast thermography to detect breast abnormalities.

ABSTRACT
Introduction: Stroke, or "cerebrovascular accident," is a medical disorder in which the brain's cells die due to insufficient blood flow. Successful stroke treatment varies according to the type of stroke, whether an infarct or a bleed, and it can be lethal without brain damage. Objective: The study aim was to compare clinical stroke diagnosis with computed tomography (CT) scan findings to determine stroke type (hemorrhagic or Ischemic). Method: This was a cross-sectional type of observational study conducted at the Department of Radiology & Imaging in Medical College for Women and Hospital (MCWH), Uttara and Catharsis Hospital, Pubail, Dhaka from January 2018 to December 2020. A total of 120 patients from the inclusion criteria were taken for the study purpose. Data of clinical diagnosis were compared individually with CT findings. Result: Out of 120 patients, 84 were males and 36 were females and they were in the age range of 20-80 years. Clinically 52 patients were suspected to have cerebral infarction, 38 intracerebral bleeds and 30 indeterminate. CT scan of the brain showed 58 cerebral infarcts, 42 intracerebral hemorrhages, 06 space-occupying lesions and 14 hemorrhagic infarcts. Conclusion: The study found that CT should be the first thing to do when a person has a stroke because it's easy, quick, and accurate at figuring out what happened.
