Pancreatic incidentaloma: incidental findings from history towards the era of liquid biopsy.A promising future in pancreatic incidentaloma detection
Peer-Reviewed Publication First Hospital of Jilin University image: On the unenhanced CT of the abdomen and pelvis (A, D), no kidney or ureteral stones are identified. As an incidental finding, discrete peripancreatic fat stranding is present around the pancreatic head which leads to an effacing of the normal parenchymal contour (short open arrow in (A))....

Prostate cancer scanning technique waives the need for pre-imaging biopsy in elderly patients
by Society of Nuclear Medicine Credit: Journal of Nuclear Medicine (2023). DOI: 10.2967/jnumed.122.265371 In elderly patients with suspected prostate cancer, a prostate-specific membrane antigen positron emission tomography (PSMA PET) CT scan can diagnose advanced disease and aid in therapy selection without the need for a biopsy. Published in the July issue of the Journal of Nuclear Medicine, this new...

PET/MRI machine learning model can eliminate sentinel lymph node biopsy in majority of breast cancer patients
by Society of Nuclear Medicine Patients with newly diagnosed breast cancer receive a PET/MRI scan to investigate axillary lymph node involvement. The radiologist then assesses whether lymph node involvement is present (nodal positive vs. nodal negative) based on easily assessable morphological and metabolic lymph node criteria. Based on these data, a random forest model is...

Colon Explorer for Automatic Imaging and Biopsying of Polyps
AUGUST 27TH, 2020 MEDGADGET EDITORS GI Millions of colonoscopies are performed every year to spot cancer as early as possible. The routine nature of these procedures and the constant need for them to be performed has led researchers at University of Colorado Boulder to develop a robotic tank-like device for traversing, imaging, and even biopsying...

Blood test to monitor cancer up to 10 times more sensitive than current methods
by University of Cambridge A new method of analyzing cancer patients’ blood for evidence of the disease could be up to ten times more sensitive than previous methods according to new research led by the University of Cambridge. In the coming years, this method and others based on this approach could lead to tests that...
