Imaging algorithm for COVID-19: A practical approach.

The global pandemic of COVID-19 pneumonia caused by the novel coronavirus (SARS-CoV-2) has strained healthcare resources across the world with emerging challenges of mass testing, resource allocation and management. While reverse transcriptase-polymerase chain reaction (RT-PCR) test is the most commonly utilized test and considered the current gold standard for diagnosis, the role of chest imaging has been highlighted by several studies demonstrating high sensitivity of computed tomography (CT). Many have suggested using CT chest as a first-line screening tool for the diagnosis of COVID-19.

Evaluation of Contrast Extravasation as a Diagnostic Criterion in the Evaluation of Arthroscopically Proven HAGL/pHAGL Lesions.

Purpose. The validity of preoperative MRI in diagnosing HAGL lesions is debated. Various investigations have produced mixed results with regard to the utility of MRI.

Lymphatic filariasis disseminating to the upper extremity.

Lymphatic filariasis is the most common cause of acquired lymphedema worldwide (Szuba and Rockson, 1998). It is endemic to tropical and subtropical regions, and its effects are devastating. With over 100 million infected persons, it ranks second only to leprosy as the leading cause of permanent and long-term disability.

The cyamella, a lost sesamoid: Normal variant or posterolateral corner anomaly?

Cyamella, an accessory sesamoid ossicle of the popliteus in the region of the proximal myotendinous junction, is an extremely unusual finding, with a paucity of current published literature describing its MR appearance. In this case study, we describe MRI findings in a 44-year-old female presenting with pain after a stretching workout. Bone edema in the cyamella, edema in the myotendinous portion of the popliteus, and pericapsular edema at the posterolateral corner were identified.

Patient-oriented cancer information on the internet: a comparison of wikipedia and a professionally maintained database.

Purpose: A wiki is a collaborative Web site, such as Wikipedia, that can be freely edited. Because of a wiki's lack of formal editorial control, we hypothesized that the content would be less complete and accurate than that of a professional peer-reviewed Web site. In this study, the coverage, accuracy, and readability of cancer information on Wikipedia were compared with those of the patient-orientated National Cancer Institute's Physician Data Query (PDQ) comprehensive cancer database.

Cross-sectional imaging of acute abdominal conditions in the oncologic patient.

Cross-sectional imaging of acute abdominal conditions encompasses a broad differential diagnosis, including traumatic, inflammatory, and infectious etiologies. In addition, an underappreciated contributor to the acute abdomen is oncologic disease and its treatment. Oncologic patients are at increased risk in the development of numerous acute abdominal conditions due to a combination of tumor invasion, sequelae of treatment, and altered immune response.

Myelofibrosis on 18F-FDG-PET/CT in a case suspicious for post-transplant lymphoproliferative disorder.

Recent studies have advocated the utility of fluorine-18 fluorodeoxyglucose-positron emission tomography (18)F-FDG-PET imaging in evaluation of various hematological disorders. We report a case of a 61-year-old man with clinical suspicion of post-transplant lymphoproliferative disorder (PTLD) where (18)F-FDG-PET/CT (computerized tomography) was helpful in identifying myelofibrosis. This paper aims to reveal the potential diagnostic value of PET/CT as an imaging modality in the evaluation of myelofibrosis.
