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.
We scan the top radiology sources so you don’t have to.
From AI breakthroughs to imaging trends, we serve up real-time radiology insights.

PSMA PET/CT Study Shows Mixed Results with Single Metastasis-Directed Radiotherapy for Oligometastatic PCa
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.

Accuracy of CT colonography with mannitol preparation for detecting synchronous lesions in obstructive colorectal cancer
Colorectal cancer (CRC) is the second leading cause of cancer deaths globally [1,2], with significant implications for public health [1,2]. A thorough preoperative assessment of the colon is essential in CRC patients due to the risk of synchronous cancer, which occurs in 4.0 % to 6.0 % of cases [2–6]. Nevertheless, in cases of obstructive tumors, optical colonoscopy (OC), the gold standard for colorectal evaluation, may be incomplete [3,6–8]. In such cases, CT colonography (CTC) is recommended b…

Semiquantitative metrics of coronary artery disease burden: Intra-individual comparison between ultrahigh-resolution photon-counting detector CT and energy-integrating detector CT
Quantitative coronary stenosis and plaque volumes have demonstrated intra-individual differences between ultrahigh-resolution (UHR) photon-counting detector (PCD)-CT and energy-integrating detector (EID)-CT. This study aimed to assess the impact of UHR PCD-CT on semiquantitative scores of coronary artery disease (CAD) burden compared with EID-CT.

Peripheral vs. central parametric mapping of the liver in single ventricle patients: Measurement location matters
Patients with single ventricle anomalies undergo staged reconstructive heart surgery, resulting in a Fontan circulation. This circulation directly connects systemic venous return to the pulmonary arteries, creating a passive pulmonary circulation that bypasses the right heart. Hemodynamic changes following Fontan circulation affect the liver, leading to Fontan-associated liver disease (FALD), which begins to occur 5–15 years after palliation [1]. Furthermore, more than 40 % of survivors 30 years…
