چکیده اصلی

An 80-year-old man underwent 18F-FDG PET/CT and 68Ga-FAPI PET/CT for a biopsy-confirmed metastatic gastrointestinal stromal tumor (GIST). While 18F-FDG PET/CT revealed intensely increased uptake in the perisplenic, right abdominal, and pelvic peritoneal implants, 68Ga-FAPI PET/CT unexpectedly showed negligible tracer uptake across all corresponding lesions.

Diffusely impaired myocardial perfusion in patients with suspected coronary artery disease: Clinical utility of relative perfusion.

BACKGROUND: In patients with suspected coronary artery disease (CAD), diffusely impaired hyperaemic myocardial blood flow (MBF) may indicate a multivessel epicardial CAD but also impaired coronary microcirculation. We assessed whether relative hyperaemic MBF-that is, the ratio of the lowest to the highest regional hyperaemic MBF-predicts obstructive CAD in patients with diffusely impaired hyperaemic MBF. METHODS: We studied 874 patient…

Spleens With Disseminated Lymphoma Exhibit Higher Standardized Uptake Value Maximum, Metabolic Tumor Volumes, and Total Lesion Glycolysis on Fluorine-18 Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography.

Standardized uptake value maximum (SUVmax), metabolic tumor volumes (MTV), and total lesion glycolysis (TLG) are metabolic parameters used to quantify tumors detected on fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT). This is a subset project from a larger pilot study where dogs diagnosed with lymphoma via lymph node aspirates were staged and monitored with serial 18F-FDG PET/CT before,…

[Expert consensus on the operational protocol for radionuclide pulmonary ventilation/perfusion scintigraphy of pulmonary thromboembolism].

Radionuclide pulmonary ventilation/perfusion (V/Q) imaging is an important non-invasive tool for diagnosing pulmonary thromboembolism (PTE) and is used for screening, follow-up, and assessment of treatment response of PTE and chronic thromboembolic pulmonary hypertension (CTEPH). Currently, hospitals in China differ in their use of planar and tomographic acquisition methods for V/Q imaging, and interpretation requires a high level of e…

Optimization of PET acquisition time for thoracic lesions in 18F-FDG PET/MRI: a retrospective analysis.

OBJECTIVE: This study aimed to define the minimum positron emission tomography (PET) acquisition time for chest PET/magnetic resonance imaging (MRI), providing image quality and lesion detectability comparable to a 20-min reference. MATERIALS AND METHODS: In this retrospective study, list-mode data from 101 patients undergoing chest 18F-fluorodeoxyglucose (18F-FDG) PET/MRI on a 3-T PET/MRI system were reconstructed to simulate 10 acqui…
