CT pioneer test-drives 256-slice scanner
The upcoming introduction of a 256-slice CT scanner promises to make major contributions to CT instrumentation, according to a Japanese radiologist who is working with a prototype of the system. From 4D cardiac imaging to CT digital subtraction angiography, 256-slice CT may result in a host of new clinical applications.

Study reaffirms value of chest radiography
As medical imaging goes increasingly high-tech, a new study out of the Netherlands indicates that the workhorse of radiology -- the chest x-ray -- remains a cost-effective exam that impacts patient management in a majority of cases.

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?
An AI model showed associations with recurrence after DCIS surgery and performed comparably to established clinical risk models.
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.

Radiology coding update for 2026
Images from two representative cases. (A-C) Images in an 82-year-old man with a calcified plaque in the proximal segment of the left anterior descending artery. (A, B) Curved planar reconstruction images from CCTA with (A) hybrid iterative reconstruction (HIR) and (B) super-resolution deep learning reconstruction (SR-DLR) show that the measured PDS was 66% for the HIR image and 42% for the SR-DLR image. (C) Quantitative analysis of the invasive coronary angiography (ICA) image (reference standard) revealed a PDS of 34% (arrow). (D-F) Images in a 37-year-old woman with a noncalcified plaque in the middle segment of the left circumflex artery. (D, E) Curved planar reconstruction images from CCTA with (D) HIR and (E) SR-DLR show that the measured PDS was 47% for the HIR image and 80% for the SR-DLR image. (F) Quantitative analysis of the ICA image revealed a PDS of 72% (arrow). Blue, red, and yellow lines in A, B, D, and E represent the proximal reference point, stenosed lesion, and distal reference point, respectively, and the insets show the corresponding cross-sectional images.

Cryoablation safe, effective in treating soft-tissue sarcoma
By Amerigo Allegretto
Percutaneous cryoablation is safe and effective for patients with recurrent or metastatic soft-tissue sarcoma after earlier treatments.
August 1, 2024
(A) Axial noncontrast CT chest image shows soft tissue mass in the anterior chest wall (arrow). The lesion was treated by percutaneous cryoablation. (B) Intraprocedural axial CT image obtained during cryoablation. The pink outline represents the target lesion and the blue outline represents ice ball. Based on review, the procedure was classified as achieving adequate ablation. (C) Axial contrast-enhanced CT chest image, obtained three months after ablation (patient’s first follow-up exam), shows involution of the target lesion without evidence of residue.
