Correlation of semi-quantitative analyses and visual scores in pulmonary perfusion SPECT/CT imaging with pulmonary function test parameters in patients with interstitial lung diseases.
Clin Radiol
January 2025
Department of Nuclear Medicine, China-Japan Friendship Hospital, Beijing, 100029, China. Electronic address:
Aim: To evaluate the correlation between semi-quantitative analyses and visual scores of pulmonary perfusion Single Photon Emission Computed Tomography (SPECT)/ Computed Tomography (CT) imaging and pulmonary function test parameters (PFTs) in patients with interstitial lung diseases (ILDs).
Materials And Methods: This retrospective study included 35 patients with ILDs from China-Japan Friendship Hospital between January 2020 and December 2022. All patients underwent pulmonary perfusion SPECT/CT imaging and a pulmonary function test.
Pulmonary embolism following bilateral quadriceps tendon repair with unilateral tourniquet use: A case report.

Case: An active healthy 68-year-old male sustained a bilateral quadriceps tendon rupture while running. He underwent a simultaneous bilateral quadriceps tendon repair in a dual-surgeon approach. The right quadriceps tendon was repaired with a tourniquet, while the left quadriceps tendon tear was repaired without one.

The nucleus tractus solitarius (NTS) contains neurons that relay sensory swallowing commands information from the oropharyngeal cavity and swallowing premotor neurons of the dorsal swallowing group (DSG). However, the spatio-temporal dynamics of the interplay between the sensory relay and the DSG is not well understood. Here, we employed fluorescence imaging after microinjection of the calcium indicator into the NTS in an arterially perfused brainstem preparation of rat (n = 8) to investigate neuronal population activity in the NTS in response to superior laryngeal nerve (SLN) stimulation.

January 2025
Department of Infectious Diseases, University Hospital of Angers, 4 rueLarrey, 49933 Angers, Cedex 9, France.
Background: Computed tomography (CT) is a critical tool for the diagnosis of pneumonia caused by SARS-CoV-2. The Delta and Omicron variants show distinct clinical features, but the radiological differences between pneumonia caused by these variants have not been extensively studied in patients with oxygen-dependent pneumonia.
Objective: To compare the radiological and clinical features of pneumonia in patients hospitalized with oxygen-dependent SARS-CoV-2 infection caused by the Delta and Omicron variants.
Cushing syndrome.

Cushing syndrome (CS) is a constellation of signs and symptoms caused by excessive exposure to exogenous or endogenous glucocorticoid hormones. Endogenous CS is caused by increased cortisol production by one or both adrenal glands (adrenal CS) or by elevated adrenocorticotropic hormone (ACTH) secretion from a pituitary tumour (Cushing disease (CD)) or non-pituitary tumour (ectopic ACTH secretion), which stimulates excessive cortisol production. CS is associated with severe multisystem morbidity, including impaired cardiovascular and metabolic function, infections and neuropsychiatric disorders, which notably reduce quality of life.
