New CT, MR scanners and AI top GE HealthCare highlights at RSNA 2023
CHICAGO -- GE HealthCare (GEHC) brought new CT and MRI scanners and a range of AI software applications to McCormick Place for RSNA 2023. CT In CT, GEHC shined the spotlight on its Revolution Ascend scanner, which was first introduced at ECR in March. With onsite detector upgrades, Ascend can be upgraded from a 20-mm coverage system for routine scanning to a 40-mm coverage system that delivers better low-contrast detectability, according to the vendor. The scanner also comes with True Enhance DL, an AI-based application that generates deep learning-based monochromatic-like images from a single-energy x-ray acquisition....

PET tracer shows promise in prostate cancer patients
CHICAGO – Gallium-68 (Ga-68) RM2-PET/MRI is better than MRI alone for detecting relapse in prostate cancer patients, according to research presented November 26 at RSNA 2023.
Moreover, the approach could help detect disease that other effective prostate cancer PET radiotracers may miss, said Heying Duan, MD, a nuclear medicine research scientist at Stanford University, during a November 26 scientific session.
“You've hear a lot about PSMA. I wanted to introduce a new player in the game: gallium-68 GRPR antagonist,” Duan told attendees, during a scientific session on prostate cancer imaging.
Several prostate-specif...

Siemens gets FDA nod for new PET/CT scanner
Siemens Healthineers has received U.S. Food and Drug Administration (FDA) clearance for its new Biograph Vision.X PET/CT scanner.The Biograph Vision.X builds on the performance of the company’s Biograph Vision family of scanners and features an industry-best time of flight (TOF) of 178 picoseconds (ps), according to the company.The scanner’s Optiso Ultra Dynamic Range (UDR) detector technology contains silicon photomultipliers (SiPMs), which enable the use of small 3.2 mm x 3.2 mm lutetium oxyorthosilicate (LSO) crystal elements. These tiny crystals provide higher spatial resolution than larger crystals, Siemens said. ...

FAPI-PET shows promise for detecting pancreatic cancer
In this study, the researchers analyzed data on 62 patients with suspected pancreatic cancer. In addition to Ga-68 FAPI-PET imaging, all patients also underwent contrast-enhanced CT, and 38 underwent F-18 FDG-PET. The primary endpoint was the association between Ga-FAPI-PET radiotracer maximum standardized uptake value (SUVmax) and histopathologic FAP expression, while secondary endpoints included comparisons to standard imaging.A male patient with suspected recurrent pancreatic cancer. Contrast-enhanced CT shows mass around superior mesenteric artery after pancreatectomy. F-18 FDG only shows discrete uptake of lesion (SU...

Road to RSNA 2023: Molecular Imaging
This is just the third year that RSNA has offered a dedicated track on nuclear medicine and molecular imaging, with eight scientific sessions covering research in prostate cancer imaging, breast cancer, cardiovascular and pulmonary imaging, and more. There will be also 30 educational courses and 14 poster sessions. Notably, this is the first year a scientific session is being offered that covers advances in AI in nuclear medicine. Presentations on PET imaging in prostate cancer – an approach that is witnessing widespread adoption – include an array of studies on prostate-specific membrane antigen (PSMA)-based radiotrac...

Ga-68 RM2-PET effective in prostate cancer relapse cases
Sunday, November 26 | 9:20 a.m.-9:30 a.m. | S1-SSNMMI01-3 | Room E350Gallium-68 (Ga-68) RM2-PET imaging should be considered in patients with biochemical recurrent (BCR) prostate cancer to aid in disease detection and management decisions, according to a study to be presented in this session.National Comprehensive Cancer Network guidelines include prostate-specific membrane antigen (PSMA) PET for the detection of BCR, yet up to 10% of cases do not express PSMA, noted presenter Heying Duan, MD, a nuclear medicine research scientist at Stanford University.Duan and colleagues developed a tracer called Ga-68 RM2, which targets...

PET predicts chemotherapy responses in breast cancer patients
PET/CT with gallium-68 (Ga-68) FAPI radiotracer can predict responses to neoadjuvant chemotherapy in breast cancer patients, according to a study published November 2 in the Journal of Nuclear Medicine. A team in Fuzhou, China, found that Ga-68 FAPI uptake on early PET/CT scans during chemotherapy indicated which patients were most likely to experience complete responses. This information can have a major impact on how patients are guided through treatment, according to the authors.“Ga-68 FAPI-PET/CT parameters can rapidly provide feedback on tumor changes after only two cycles of chemotherapy,” wrote first author Ling...

What Are the Common Types of Craniosynostosis?
Discussion
Usually when an infant is born the fontanelles and sutures remain open allowing the cranial bones the ability to move and undergo molding. This assists in delivery and molding from delivery usually resolves within hours to a few days.
Positional plagiocephaly (also called deformational plagiocephaly) usually occurs after birth (usually in the first few weeks) due to mechanical factors including positioning of the infant’s head such that little repositioning occurs (i.e. bottle feeding only on same side, placement in crib on same side, placement always on infant’s back with no prone placement, etc.)...

FAPI-PET bests FDG-PET in detecting gastrointestinal cancer
Fibroblast activation protein inhibitor (FAPI)-PET/CT appears superior to standard FDG-PET/CT for detecting gastrointestinal cancer, with higher radiotracer uptake seen in most tumors, according to a study published October 26 in the Journal of Nuclear Medicine. In a clinical trial, researchers in Xiamen, China, compared the two approaches for detecting primary and metastatic tumors in patients with confirmed gastric, liver, or pancreatic cancer.“The use of F-18 FAPI-74 PET/CT is expected to improve the diagnosis of gastrointestinal cancer and contribute to individualized patient care,” wrote senior author Haojun Chen,...

PET/MRI reveals effects of COVID-19 vaccines in children
In this study, they hypothesized that F-18 FDG-PET/MRI may reveal activation in the thymus in pediatric oncology patients in addition to lymph node reactions.The group assessed scans of six children with extrathoracic cancer before and after COVID-19 vaccination. They analyzed both PET and MRI biomarkers, such as uptake of F-18 FDG radiotracer (maximum standard uptake values, or SUVmax), mean apparent diffusion coefficient on MRI, and size of the thymus and axillary lymph nodes.There was a significant increase in the metabolic activity in the ipsilateral axillary lymph nodes across all patients after COVID-19 vaccination, ...
