Hydration before contrast cuts CIN in high-risk patients
Even patients with advanced kidney disease can steer clear of contrast-induced nephropathy (CIN) if given plenty of hydration, say researchers from the Netherlands. Results from the study of nearly 1,000 patients with stage 3 or 4 kidney disease were published in the June issue of Radiology.

ISCT: Many paths, some steep, lead to cardiac CT accreditation
SAN FRANCISCO - Cardiac CT credentialing comes from several organizations in the U.S. and in various levels corresponding to different training and proficiency achievements. But doctors can't expect to read with the best unless they're prepared for a lot of training, a CT expert said at the International Society for Computed Tomography (ISCT) meeting.

ISCT: Dose-reduction technique explores reader perceptions
SAN FRANCISCO - An evolving CT dose-reduction technique looks beyond simulated image noise as a measure of image quality, and instead aims to optimize dose based on what the radiologist needs to see, according to a presentation on Monday at the International Society for Computed Tomography (ISCT) annual meeting.

Postmortem CT shows cause of death after acute chest pain
Postmortem CT angiography combined with image-guided biopsy can nearly always determine the cause of death in patients who succumb after acute chest pain, a question that has often gone unanswered, according to a Swiss study published in Radiology.

Repeat VC after 5 years shows few advanced lesions
Individuals who were negative in their first round of virtual colonoscopy screening tend to stay that way at repeat screening five years later. The results are a positive sign that VC is a good way to detect significant lesions before they can advance to malignancies.

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).

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.

Ultrafast MRI exam bests standard MRI for classifying breast cancers
By Amerigo Allegretto
An ultrafast MRI-based radiomics exam performs just as well as standard MRI and isn’t dependent on radiologist experience.
January 28, 2025
Ultrafast and standard MRI in a 30-year-old woman with triple-negative invasive ductal carcinoma. (A) Ultrafast MRI taken 16.8 seconds after contrast agent injection. (B) Standard MRI taken 58.8 seconds after contrast agent injection. Both images show an oval-shaped, irregular marginated, rim-enhancing mass in the left outer breast. For 3D tumor segmentation, the entire enhanced tumor margins were drawn from top to bottom of each tumor in axial views of U2 phase postcontrast ultrafast MRI and the initial phase postcontrast standard MRI. Among the 14 ultrafast images, U1 is the first phase in which the signal intensity of the hotspot region of interest of the tumor is 10% higher than the average signal intensity of unenhanced images. U2 is the immediate next phase of U1 and the well-established tumor enhancement time.
