Positron adds PET cardiology software

Apr 11, 2006

PET vendor Positron said it has finalized an agreement with the University of Texas at Houston and the Weatherhead PET Center, also of Houston, to develop and commercialize software developed for diagnostic and management needs in coronary artery disease.

The software includes the validated quantification of coronary blood flow images by PET longitudinal gradient analysis and homogeneity algorithm (LGA/HA). This algorithm helps to determine severity of coronary disease as the objective noninvasive basis for or against coronary bypass surgery or stent procedures. In addition, it provides an automated objective analysis of CT or invasive coronary angiograms, and a comprehensive database management system, according to Houston-based Positron.

In conjunction with Positron's application development efforts, the firm has also released Positron version A3.7 software. The software release incorporates the LGA/HA algorithms, a cardiac normal database, and enhancements for quantification, usability, and predictability.

F-18 FDG and Ga-68 FAPI-46 images of a 51-year-old woman with adenocarcinoma with lepidic growth pattern in right upper lobe. (A) Maximum-intensity-projection PET images. The lesion had F-18 FDG uptake below blood pool level but was strongly Ga-68 FAPI-46-positive. CT-guided biopsy led to pathologic diagnosis of adenocarcinoma, and the patient was treated by stereotactic body radiation therapy because of functional inoperability.

ChatGPT powered by GPT-4 and using DALL-E−3 was asked to generate an image for teaching purposes that demonstrated: a nuclear medicine bone scan with skeletal metastases (top left); coronary artery disease (top right); an F-18 FDG-PET scan of the brain with Alzheimer's disease (bottom left); and an x-ray showing a fracture (bottom right). These are misleading for educational purposes and for patients who may be searching for information. Image and caption courtesy of Radiography.

PET/MRI may improve diagnosis of Cushing disease

PET/MRI could become the diagnostic method of choice over MRI alone for identifying small pituitary tumors associated with Cushing disease.

March 29, 2024

T1-weighted postgadolinium MR images (A and C) and F-18 FET-PET/MR images (B and D) centered at pituitary before (A and B) and after (C and D) transsphenoidal surgery. This patient with Cushing disease showed clear focal uptake (B) but no clear lesion on previously obtained and accompanying MRI (A). Postoperative tissue analysis did confirm resection of small pituitary adenoma/PitNET, and postoperative F-18 FET-PET showed no residual uptake (D).
