ACC news: CTA dose varies widely, could be lower

CHICAGO - Substantial variation in patient radiation dose can occur during cardiac CT angiography (CTA) studies at different sites around the world, researchers said this week at the 2008 American College of Cardiology (ACC) meeting. The researchers added that the vast majority of CT sites are not using recently released techniques to reduce radiation dose.

Ultrasound contrast agents appear safe despite FDA warning

CHICAGO - U.S. researchers at this week's American College of Cardiology (ACC) meeting say that ultrasound contrast agents are safe, despite a recent U.S. Food and Drug Administration (FDA) black box warning regarding the use of several commercially available ultrasound contrast agents.

Interventionalists: Proceed with caution for mechanical blood clot removal

The best predictor of a good recovery after an ischemic stroke is how successfully the patient can be revascularized, according to the results of a multicenter trial that looked at the correlation between restoration of blood flow and outcomes. Neurointerventionalist Dr. Christopher Zylak recently offered his take on the trial, and discussed how to get the best treatment outcomes for the patient.

At-risk liver cancer patients should get US screening

Hepatocellular carcinoma is becoming more common in patients with liver disease, and ultrasound remains the key screening modality for high-risk patients, according to Dr. Eugene Schiff of the Center for Liver Diseases at the University of Miami. He recommends ultrasound screening and surveillance every six months for these patients.

Which modality for AAA? Depends on what you seek, says ISET speaker

While ultrasound can handily spot an abdominal aortic aneurysm (AAA), more sophisticated imaging is needed to plan treatments such as open surgery or endovascular therapy, according to Dr. Bart Dolmatch, chief of interventional radiology at the University of Texas Southwestern Medical Center at Dallas. He recently discussed the roles CT and MRI play in assessing AAA.

Imaging set to play pivotal role for delivering molecular therapeutics

Treatment specialists experimenting with molecular medicine will achieve more targeted results by injecting drugs with imaging guidance, according to Dr. Lawrence Hoffmann, chief of interventional radiology at Stanford University Medical Center in California. In a recent presentation, Hofmann stressed that interventional oncology and interventional regenerative medicine will pair imaging and molecular therapeutics, as imaging plays a pivotal role in therapeutic angiogenesis.

CAD spots missed breast cancers without inflating recalls

By adding computer-aided detection (CAD) to its mammography exams, a team from a Salt Lake City-based institution found that it was able to boost cancer detection without a significant increase in the recall rate. The group tracked mammographic findings of more than 43,000 patients over a one-year period.

Signs of iron overload on cardiac MRI guide thalassemia therapy

Iron cardiomyopathy is the leading cause of death in thalassemia patients. But treatment with the chelating agent deferasirox appears to improve cardiac function among patients with thalassemia based on the presence of cardiac iron on MRI T2* scans, according to the preliminary results of an ongoing multicenter trial.

Screening mammograms for elderly women encouraged

Women at age 70 have a life expectancy of 15.9 years, according to statistics compiled by the Centers for Disease Control and Prevention (CDC). As the population ages, the risk for developing breast cancer increases. A review of mammography outcomes among elderly women shows that breast cancer screening for this population should be encouraged.

Adding MBI to DBT finds more breast cancers

By Amerigo Allegretto

Adding molecular breast imaging (MBI) to DBT screening leads to more invasive cancers detected in women with dense breasts.

September 23, 2025

Images in a 62-year-old woman who presented for screening. (A) Image from DBT screening (the synthesized 2D mediolateral oblique view of the left breast is shown) at year on was interpreted as negative and showing heterogeneously dense breast. (B) Image from molecular breast imaging screening (mediolateral oblique view) at year one reveals a 0.9-cm non-mass focal area of uptake in the left breast (arrow). (C) Targeted ultrasound scan (transverse image) shows a suspicious mass in the 3-o’clock position of the left breast, 4 cm from the nipple. Ultrasound-guided core biopsy and lumpectomy revealed a 0.9-cm grade 2 invasive ductal carcinoma, an estrogen receptor–negative, progesterone receptor–negative, human epidermal growth factor receptor 2–negative lesion, with two sentinel nodes negative (N0).

An example of a typical BgRT plan: A) PET scan on diagnostic PET/CT and B) X1 PET-Linac for patient #15 with a PET avid rib metastasis with GTV size= 3.1 cc, PTV = GTV + 5mm, BTZ (biological tracking zone) = PTV + 5 mm, AC = 14.33 kBq/mL and NTS = 21.04. Red, magenta, and green contours represent GTV, PTV, and BTZ. C) Dose distribution and D) bounded-DVH of a BgRT plan are displayed for the same patient. The bounded Dose-Volume Histogram (DVH) models variations in BgRT delivery, encompassing fluctuation in target background signal variation, target localization and dose delivery uncertainties.
