The knee is a very important joint and injuries affecting it may cause significant disability and discomfort to the patient. Despite a variety of methods available to assess injuries of the knee joint, Magnetic Resonance Imaging (MRI) continues to play a major role. This study evaluated the spectrum of MRI findings in a relatively low resource environment, with limited access to MRI modality. The outcome should justify further investment in MRI services in this locality. The study involves retrospective analysis of MRI reports of 198 clinically symptomatic patients referred for imaging in a Port-Harcourt. All examinations were performed using GE BRIVO MR 235 machine with 0.35 Tesla field strength in a well-coupled standard knee coil. All images were analyzed for normality or otherwise and radiological reports generated by competent radiologists. The most common findings are traumatic in origin, notably cruciate ligament tears (37.37%) and meniscal tears (33.3%) as well as quadriceps tendon tears (3.03%). The medial meniscus and anterior cruciate ligaments were more frequently involved. Furthermore, patients in the 3rd and 4th decade of life were more commonly involved, with a male preponderance. The less common findings of Synovial chondromatosis, cyst-like lesions, tumors and loose bodies, all buttress the importance of routine MRI in atraumatic cases. The spectrum of MRI findings in this study is a reflection of growing interest and confidence in MRI of the diseased knee joint in our environment. The outcome would be a justification for future investments in MRI. Keywords: Magnetic Resonance Imaging, knee injuries, tibial meniscal tears, incidental findings

Background: The novel coronavirus disease (COVID-19) is usually under diagnosed in resource-constrained countries as Africa. Although Real-time-reverse-transcription polymerase chain reaction (RT-PCR) testing is considered to be the gold standard tool to diagnose or screen for COVID-19, chest imaging is a valuable tool to support the diagnosis of COVID-19 pneumonia. Therefore, Radiologists usually play an important role in the diagnosis of COVID-19 pneumonia, especially in resource-constrained environments. This study aimed to evaluate the patterns of chest CT findings in covid-19 pneumonia and to emphasize its diagnostic value in coronavirus disease. Materials and Method: This study was a retrospective cross-sectional study conducted in a reputable diagnostic center in Port Harcourt and comprised of 13 chest CT images diagnosed of Covid-19 pneumonia that met the inclusion criteria set for this study. All the chest CT examinations were performed by registered radiographers on a 64-slice CT scanner (GE Optima CT660, GE medical systems). Results: Chest CT findings in patients with confirmed covid-19 infection was evaluated and the results revealed that 13 (100%) had GGO. Out of 13 patients with GGO, bilateral distribution of the opacities was found in 11(84.62%), followed by peripheral opacities 9(69%) and the least 2 (15.38%) was unilateral distribution. Conclusion: The commonest chest CT appearance of covid-19 pneumonia is bilateral GGO with a predilection for the lower lobes of the lungs. Radiologists and clinicians should take cognizance of imaging appearances and diagnostic capabilities of Chest CT in covid-19 pneumonia, especially in the context of the current pandemic.
