A Multicentre Clinical Trial Evaluating a Drop-in Gamma Probe for Minimally Invasive Sentinel Lymph Node Dissection in Prostate Cancer.

Background: This study evaluated the safety and performance of a drop-in gamma probe for prostate cancer (PCa) sentinel lymph node biopsy (SeLNB) in a prospective, open-label, multicentre, single-arm clinical trial.

Objective: The main objective was to determine the sentinel lymph node (SeLN) detection rate with the drop-in gamma probe system. The secondary objectives were overall performance and safety.

Incidental 68Ga-DOTATOC PET/CT Uptake in Hemorrhagic Transformation of Stroke in a Patient With Cervical Paraganglioma.

We present a case of a 75-year-old woman with clinical suspicion of stroke whose cranial CT showed ischemic changes in right precentral region, without visible vascular occlusion, and a right vagal lesion suggestive of paraganglioma. Two weeks later, 68Ga-DOTATOC PET/CT with IV iodine-based contrast administration (Biograph 6 True Point equipment; Siemens) was performed for characterization of this lesion and staging. Intraparenchymal 68Ga-DOTATOC uptake was visualized in right frontal lobe suggestive of hemorrhagic transformation of the previous stroke.

Clinical relevance of incidental focal breast uptake on fluorine-18 fluorodeoxyglucose PET/computed tomography studies: an experience in a high-load center of Spain.

Aim: We aimed to determine the frequency and clinical significance of breast incidental uptake (BIU) detected through fluorine-18 fluorodeoxyglucose (18F-FDG) PET/computed tomography (CT) in a single, high-load center.

Patients And Methods: In this retrospective study, we analyzed a total of 13 763 PET/CT studies performed from January 2017 to January 2020. After excluding 3148 scans, the maximum standardized uptake value (SUVmax) and maximum diameter (cm) of each BIU were measured.

Comparison of 99mTc-Tilmanocept and Hybrid Indocyanine Green-99mTc-Albumin Nanocolloid Drainage in a Patient With Melanoma in the Scalp.

We present the planar lymphoscintigraphies and SPECT/CT images of a 60-year-old man diagnosed as having melanoma (Breslow 1.8 mm) in left parietal scalp, close to head midline. Sentinel lymph node biopsy using Tc-tilmanocept was performed, but the surgery was canceled.

Assessment of extra-parenchymal lung involvement in asymptomatic cancer patients with COVID-19 pneumonia detected on F-FDG PET-CT studies.

Background: Lung involvement in patients with coronavirus disease 2019 (COVID-19) undergoing PET-CT has been previously reported. However, FDG uptake outside lung parenchyma was poorly characterized in detail. We evaluated the extra-parenchymal lung involvement in asymptomatic cancer patients with COVID-19 pneumonia through F-FDG PET-CT.
