While AI-enabled hippocampal segmentation on MRI offered a 95 percent AUC for differentiating between Alzheimer’s disease and normal controls in a 27-study meta-analysis, it offered significantly lower sensitivity and specificity in differentiating mild cognitive impairment.

For DBT breast cancer screening, 47 percent of radiologist-only flagged false positives involved mass presentations whereas 40 percent of AI-only flagged false positive cases involved benign calcifications, according to research presented at the recent American Roentgen Ray Society (ARRS) conference.

For patients with recurrent or metastatic prostate cancer, new research findings showed no significant difference in the sensitivity of 18F-piflufolastat PET/CT between patients on concurrent hormone therapy and those without hormone therapy.

Irrespective of age or O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation status, gross total resection of IDH wild-type glioblastomas was associated with a median overall survival of 32.6 months, according to new MRI research.

In comparison to American Joint Committee on Cancer (AJCC) TNM staging, an emerging CT-based scoring system for assessing early recurrence of pancreatic ductal adenocarcinoma demonstrated over a 22 percent higher AUC in testing and external validation cohorts in a new study.

The combination of the Aurora SPECT/CT system with AI-enabled Clarify DL image reconstruction reportedly offers the potential of enhanced image quality and streamlined workflows in nuclear medicine.

In a second part of a new podcast episode on recently published research on projected radiation-induced cancers from computed tomography (CT) scans, Mahadevappa Mahesh, MS, Ph.D., and Joseph Cavallo, M.D., offer current perspectives on cardiac CT dosing, AI advances and the importance of teamwork in ensuring appropriate dosing for CT.

While PSMA PET/CT revealed an 87 percent local remission rate after metastasis-directed radiotherapy for oligometastatic prostate cancer in a new study, researchers also found that 80 percent of patients had biochemical progression at a median 32-month follow-up.
