Gastroenterologist beats radiologist in dual-prep VC match
In a face-off that's making waves on both sides of the Pacific, a board-certified gastroenterologist outperformed a board-certified radiologist in detecting polyps with virtual colonoscopy, researchers report.

VC radiation dose holds steady overall despite dose modulation
The radiation dose from virtual colonoscopy (VC) hasn't dropped much since the introduction of dose modulation software on CT scanners, largely because VC providers use it only half the time, according to a new study from the Netherlands, which also demonstrated significantly lower doses for VC screening protocols compared to daily practice protocols.

Using coronary CTA first versus SPECT cuts costs
SPECT myocardial perfusion imaging has long been the primary modality for evaluating coronary artery disease. But research based on payor data covering millions of patients found that initial evaluation with coronary CT angiography cut costs significantly over a year's time for patients without coronary artery disease and the patient cohort overall.

Coronary calcium still matters
In light of radiology's fervent focus on coronary CT angiography (CTA) and unstable coronary artery plaque, does coronary artery calcium even matter anymore? It does, according Dr. J. Jeffrey Carr of Wake Forest University in Winston-Salem, NC. He recently debunked some myths about calcium at the 2008 International Symposium on Multidetector-Row CT.

Automated polyp measurement cuts variability
A new study from the Netherlands found that manual polyp measurements in virtual colonoscopy were a bit more accurate than an automated process based on polyp protrusion measurements. The automated scheme still came out ahead, however, because it eliminated interobserver variability.

Low tube current, modulation reduce pediatric CTA dose
Dialing down the x-ray tube current and activating tube-current modulation made a huge difference in the radiation dose for children undergoing coronary CT angiography (CTA), according to a new study in the American Journal of Roentgenology. The reduced-dose acquisition protocols had no significant negative effect on image quality and were, in fact, hardly noticeable, researchers said.

CMS launches comment period for VC coverage
Just weeks after the American Cancer Society recommended virtual colonoscopy for colon screening, Medicare is taking up the task by launching an analysis of the technology that could eventually lead to U.S. reimbursement for nationwide screening.

FAPI-PET shows promise in head and neck cancer patients
By Will Morton
In a comparative imaging trial, FAPI-PET/CT outperformed FDG-PET/CT in detecting primary tumors in patients with head and neck cancer.

PET/CT and MR images of a 72-year-old woman. (A) F-18 FDG-PET images (left and top) and PET/CT images (bottom) shown in coronal, sagittal, and axial views (from left to right), demonstrated a metastatic lymph node of the right neck with intensive metabolic activity (black arrow, SUVmax, 30.1) but presented no evidence for primary tumor. (B) Ga-68 FAPI-PET images (top and right) and PET/CT images (bottom), shown in axial, sagittal, and coronal views (from left to right), also detected metastatic lymph node with high Ga-68 FAPI tracer activity (black arrow, SUVmax, 16.3). There was intensive uptake of Ga-68 FAPI in palate (red arrow, SUVmax, 11.3). (C) T1-weighted, T2-weighted, and contrast-enhanced T1-weighted MRI also presented no evidence for primary tumor. Subsequent surgery confirmed mucoepidermoid carcinoma of palate. Image courtesy of the Journal of Nuclear Medicine.

Examples of quantification of background parenchymal enhancement (BPE) over fibroglandular tissue (FGT) on breast DCE-MRI scans from three patients. Images from left to right are the first postcontrast T1-weighted images, automated segmentation of the right and left breasts (red contours) and semiautomated tumor segmentation (yellow), automated segmentation of FGT (green), and quantification of BPE (purple) over the FGT regions. (A) Images of a 48-year-old woman diagnosed with invasive ductal carcinoma and assigned a low-risk Oncotype DX distant recurrence risk score (score, 13). The BPE measures at 20% cutoff value were ipsilateral absolute BPE within FGT relative to FGT volume (%BPEF/F) of 9.8% and contralateral %BPEF/F of 9.5%. (B) Images of a 60-year-old woman diagnosed with invasive ductal carcinoma and assigned an intermediate-risk Oncotype DX distant recurrence risk score (score, 19). The BPE measures at 20% cutoff value were as follows: ipsilateral %BPEF/F of 13.3% and contralateral %BPEF/F of 14.7%. (C) Images of a 54-year-old woman diagnosed with invasive ductal carcinoma and assigned a high-risk Oncotype DX distant recurrence risk score (score, 30). The BPE measures at 20% cutoff value were as follows: ipsilateral %BPEF/F of 34.1% and contralateral %BPEF/F of 14.5%. Image courtesy of the RSNA.
