Dual-tracer PET/CT shows promise in liver cancer patients

AuntMinnie

A group led by researchers at the University of Hong Kong in China found the approach detected 12% more disease in patients undergoing staging than CT or MRI and resulted in a change in treatment in a significant number of cases. The results validate the emerging technique, the group noted.

Terran Biosciences Receives FDA Clearance for NM-101, the Industry’s First Software for the analysis of Neuromelanin-sensitive MRI

Imaging Technology

While neuromelanin was first described in the 19 th century, researchers have elucidated its possible role as a biomarker for neurological disorders such as Parkinson’s disease in the last two decades. Cassidy, “it allows us to obtain potentially useful adjunctive information about many other diseases such as Alzheimer’s disease, and PTSD.”

PSMA PET/CT Waives the Need for Pre-imaging Biopsy in Elderly Patients

Imaging Technology

milla1cf Tue, 08/15/2023 - 16:28 August 15, 2023 — In elderly patients with suspected prostate cancer, PSMA PET/CT can diagnose advanced disease and aid in therapy selection without the need for a biopsy. Compared with patients who did have a pre-imaging biopsy, these patients were older with worse clinical status and had higher PSA levels.

Novel Technique Has Potential to Transform Breast Cancer Detection

Imaging Technology

Since almost half of the screening population has dense breasts, many of these patients require additional breast imaging, often with MRI , after mammography. Low-dose positron emission mammography (PEM) is a novel molecular imaging technique that provides improved diagnostic performance at a radiation dose comparable to that of mammography.

Low-dose PEM shows promise in breast cancer detection

AuntMinnie

PEM is one molecular breast imaging method that has shown promise in lowering the number of false-positive cases, owing to its superior specificity over MRI. However, PEM’s higher radiation dose has steered radiologists away from using the modality. On 100 sets of bilateral PEM images, 24 (96%) of 25 cancers were identified.

Road to RSNA 2024: Ultrasound Preview

AuntMinnie

Ultrasound proponents will have the opportunity to present and see the modality’s versatility in helping detect and diagnose pathologies such as liver cancer, breast cancer, and thyroid cancer. They can also highlight the resulting benefits that are possible, of course, without the ionizing radiation of some other imaging modalities.
