The University of Texas (UT) Southwestern Medical Center in Dallas has opened its new cyclotron facility to produce isotopes for medical imaging and cancer research.

The cyclotron is expected to help with a variety of studies and clinical trials across many areas, including cardiology, immunology, psychiatry, biochemistry, and pharmacology.

The cyclotron facility is part of the Bill and Rita Clements Advanced Medical Imaging Building at UT Southwestern.

PET predicts chemotherapy responses in breast cancer patients

PET/CT with gallium-68 FAPI radiotracer can predict responses to neoadjuvant chemotherapy in breast cancer patients.

November 8, 2023

Representative Ga-68 FAPI-PET/CT images of 48-year-old woman who had left invasive ductal carcinoma and who achieved pathologic complete response (pCR). (A) Baseline maximum-intensity projection (MIP) image demonstrated primary lesion (red arrowhead; SUVmax, 26.72) and Ga-68 FAPI-avid lymph node in left axilla (red arrows). (B) MIP image after two cycles of neoadjuvant chemotherapy (NAC) showed that primary lesion (red arrowhead; SUVmax, 8.87) and axillary lymph nodes (red arrow) were reduced in size and radioactivity uptake. (C and D) Representative images of lab tissue staining for FAP before NAC showed strong FAP-positive staining in stromal cells (C), which was significantly decreased on tumor bed after six cycles of NAC (D).

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.

October 31, 2023

Nine representative patients who underwent F-18 FDG and F-18 FAPI-74 PET imaging. F-18 FAPI-74 PET outperforms F-18 FDG-PET in detecting primary tumors (patients 11, 39, 50, 58, 79, and 101; solid black arrows), local recurrences (patient 4; blue arrows), abdomen LN metastases (patients 4 and 50; green arrows), intrahepatic metastases (patient 50; red arrows), bone metastases (patient 85; arrowheads), and peritoneal metastases (patients 4, 11, 85, 97, and 101; dotted arrows).
