Prediction of Motor Recovery after Stroke by Assessment of Corticospinal Tract Wallerian Degeneration Using Diffusion Tensor Imaging.

To predict motor recovery after stroke by detection of diffusion tensor imaging (DTI) fractional anisotropy (FA) changes of corticospinal tract (CST) and correlate findings with clinical scores to provide more effective treatment and rehabilitation. Thirty patients with cerebral stroke were enrolled and underwent conventional magnetic resonance imaging and DTI at admission and 1 month after stroke. Mean diffusivity (MD), FA, FA ratio (rFA), and fiber number (FN) values of CST were calculated at the pons at admission and after 1 month of stroke.

Chest computed tomography imaging features in patients with coronavirus disease 2019 (COVID-19).

Objective: To analyze computed tomography (CT) features of symptomatic patients with coronavirus disease 2019 (COVID-19).

Methods: Ninety-five symptomatic patients with COVID-19 confirmed by reverse-transcription polymerase chain reaction from 1 May to 14 July 2020 were retrospectively enrolled. Follow-up CT findings and their distributions were analyzed and compared from symptom onset to late-stage disease.

COVID-19 Viral Pneumonia Complicated with Acute Pulmonary Embolism: A Descriptive Study.

Objective: To evaluate acute pulmonary embolism in patients with 2019 novel coronavirus (COVID-19) pneumonia using pulmonary CT angiography. . From 95 symptomatic patients confirmed with COVID-19 by RT-PCR from 1 May to 14 July 2020 in Dallah Hospital, Riyadh, Saudi Arabia, CT angiography was done for 25 patients suspected to have pulmonary embolism and have no contraindication for contrast study.

Ectopic pregnancies in caesarean section scars: 5 years experience.

Purpose: The aim of the study is to evaluate our 5 years experience in diagnosis and treatment of ectopic pregnancy developing in a Caesarean section scar.

Subjects & Methods: The study included twenty-one women, diagnosed with a Caesarean scar ectopic pregnancy (CSEP) in the first trimester, which was confirmed by ultrasound and treated in our hospital during 5 years between 2012 and 2016. The clinical presentations, imaging findings, and treatment outcomes of all these pregnancies were recorded.
