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.

Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Could AI scoring help with managing DCIS?
Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.
