CTA, not CTP, makes the call for ischemic stroke treatment
CT perfusion (CTP) imaging of the brain brings multiple diagnostic benefits for ischemic stroke patients, but it's not needed when deciding whether to revascularize, according to neuroradiologist Dr. Michael Lev from Massachusetts General Hospital. CT angiography (CTA) can also be used as a surrogate for diffusion-weighted MRI to determine infarct size.

Radiation doses OK in 1st Thailand pediatric CT survey
Researchers in Thailand have published the country's first pediatric radiation dose survey based on data from three university hospitals. The group found that CT dose levels generally are reasonable for brain, chest, and abdominal exams.

CT study ties pulmonary artery size to COPD symptoms
A study published online September 3 in the New England Journal of Medicine found that pulmonary artery enlargement as seen on CT scans is closely correlated with the development of exacerbated chronic obstructive pulmonary disease (COPD) symptoms, providing a potentially strong predictor of symptom onset.

2 technologists read VC studies as well as 1 radiologist
When it comes to reading virtual colonoscopy studies, a radiologic technologist is no match for a trained radiologist. But two technologists are another matter entirely: They were equivalent to, and maybe slightly better than, a single radiologist, according to a new study in Radiology.

ESC: 320-detector-row CTA plus perfusion helps triage patients
A two-step heart test consisting of 320-detector-row CT angiography (CTA) followed by CT perfusion helps separate patients who need invasive angiography from those who do not, according to results of the international CORE 320 study presented on Monday at the European Society of Cardiology (ESC) meeting in Munich.

ESC: Fractional flow reserve CT finds vessels causing ischemia
Fractional flow reserve CT in patients with significant stenosis can distinguish those with coronary artery disease who need revascularization from those who don't, concluded a study presented on Sunday at the European Society of Cardiology (ESC) meeting and published concurrently in the Journal of the American Medical Association.

New risk model predicts need for CT lung screening
A new risk model for lung cancer goes where Framingham dared to tread for heart disease: providing sophisticated assessments of which individuals would most likely benefit from CT lung screening, according to a report in the August 21 issue of Annals of Internal Medicine.

August 16, 2024
Sagittal, coronal, and axial fused Tc-99m PYP-SPECT/CT images of a 93-year-old male at baseline and after two years of tafamidis 61 mg daily by mouth therapy. Tc-99m PYP images are shown in color and CT images are shown in grey scale. These images show a reduction in visual grade from an initial grade of 3 (myocardial uptake > rib uptake) to a follow-up grade of 1 (myocardial uptake < rib uptake). Quantitative metrics decreased significantly as well.

Dynamic PET/CT and pathologic images for a 66-year-old male participant. (A) Axial dynamic PET/CT image acquired during intravenous administration of Ga-68 PSMA-11 demonstrates the hypermetabolic primary prostatic tumor. The right-sided portion of the lesion used for volume of interest (VOI) analysis is outlined in pink, reflecting the margins seen on a prior T2-weighted MRI scan. Tumor radiotracer uptake extends across midline into the left anterior apex (*). (B) Axial dynamic PET/CT image acquired during selective right prostatic arterial administration of Ga-68 PSMA-11 demonstrates intense radiotracer uptake in the VOI outlined in pink. There is comparatively minimal uptake in the unperfused left-sided portion of the tumor (*). The arterial sheath and catheters in the right groin are partially visualized (arrow). (C) Photomicrograph (hematoxylin-eosin stain; unmagnified) of the prostatic apex after radical prostatectomy. The midline (dotted line) and dominant tumor margins (solid line) are shown. Small additional areas of carcinoma (■) without T2-weighted MRI correlates were also identified at pathologic examination.
