Low-dose chest CT presentation and dynamic changes in patients with novel coronavirus disease 2019.

Objective: To investigate the low-dose chest computed tomography (CT) presentation and dynamic changes in patients with novel coronavirus disease 2019 (COVID-19) to improve understanding of this highly infectious disease.

Methods: The clinical and CT data of 16 patients with COVID-19 were retrospectively analyzed. Dynamic CTs were performed continuously after admission.

A typical computed tomography presentations of coronavirus disease 2019.

Objective: This study aimed to investigate the atypical computed tomography (CT) presentations of coronavirus disease 2019 (COVID-19) patients to comprehensively understand this highly infectious disease.

Methods: The clinical and chest CT imaging data of 16 patients diagnosed with COVID-19 were retrospectively analyzed, and patients with atypical CT presentations were selected for analysis and review.

Results: Of the 16 patients, 6 had atypical CT presentations, including 2 with faint ground glass opacities, 2 with single nodule, 1 with predominantly linear opacities, and 1 with predominantly reticular opacities.

Computed tomography findings in a case of coronavirus disease 2019.

Coronavirus disease 2019 (COVID-19), which is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is mainly characterized by pulmonary inflammation. The preferred imaging modality is chest computed tomography (CT) which plays an important role in early diagnosis, quarantine, and treatment as well as in the evaluation of therapeutic efficacy. We report the imaging data from a confirmed case of COVID-19 admitted to our hospital.

Imaging Diagnosis of Von Hippel-Lindau Syndrome.

Introduction: Von Hippel-Lindau (VHL) syndrome is a group of rare autosomal dominant hereditary diseases that involve multiple organs. Due to its high recurrence rate and complex and diverse clinical manifestations, VHL is prone to being either misdiagnosed or missed entirely. Therefore, patients with VHL syndrome have a poor prognosis.

Magnetic Susceptibility in Normal Brains of Young Adults Based on Quantitative Susceptibility Mapping.

Objectives: To explore the changes of brain susceptibility of different sides and genders in healthy young adults using quantitative susceptibility mapping (QSM).

Methods: Totally 42 healthy young right-handed adults underwent conventional brain magnetic resonance imaging and QSM scans, and the susceptibility maps were obtained by image post-processing software. Then the regions-of-interest (ROI) of bilateral frontal gray matter (FGM), frontal white matter (FWM), caudate (CA), globus pallidus (GP), putamen (PU), thalamus (TH), substantia nigra (SN), red nucleus (RN), dentate nucleus (DN), pons (PO), and corpus callosum (CC) were manually drawn to obtain magnetic susceptibility on the susceptibility maps.

Significance of imaging findings in the diagnosis of heterotopic spleen-an intrapancreatic accessory spleen (IPAS): Case report.

Rationale: Accessory spleen (Heterotopic/Ectopic) or splenunculus has been attributed to the failure of the fusion of splenic primordial buds-derived from dorsal mesentery (mesodermal mesenchymal in origin) during the 5th week of embryonic organogenesis or to an extreme degree of splenic lobulation with pinching off of the spleen tissue. The most common locations for accessory spleens are the hilum of the spleen followed by adjacent to the tail of the pancreas. The patients usually present with no clinical symptoms.
