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.

FES-PET effective for staging breast cancer in phase II trial
By Will Morton
F-18 fluroestradiol (FES)-PET/CT appears as effective as standard imaging for staging women with estrogen receptor-positive locally advanced breast cancer or evaluating suspected recurrence.
July 26, 2024
The patient was a woman in her 50s with suspected recurrence of invasive lobular breast cancer. A, maximum intensity projection image from FDG-PET/CT demonstrating avid foci in the chest (red arrow). Transaxial CT (B) and transaxial fused FDG-PET/CT image (C) showing that the chest avidity corresponds to FDG-avid lung nodules (red arrows) suspicious for malignancy. The lung nodule was subsequently biopsied but found to represent benign granulomatous inflammation and thus a false positive on FDG-PET/CT. D, maximum intensity projection image from FES-PET/CT demonstrating multifocal uptake suspicious for malignancy. E, transaxial CT and fused FES-PET/CT demonstrating no FES-avidity in the biopsy proven benign granulomatous lung nodules (red arrows), thus true negative on FES-PET/CT. FES-avidity in nodes (white arrow) is suspicious for malignancy. F, transaxial CT and fused FES-PET/CT demonstrates gastric avidity (blue arrow) suspicious for malignancy. G, transaxial CT and fused FES PET/CT demonstrates FES-avid osseous foci (yellow arrow) suspicious for malignancy. This osseous focus was subsequently biopsied and proved to be an osseous metastasis and thus true positive on FES-PET/CT.
