CT perfusion gauges sarcoma treatment response
Sunday, November 28 | 11:25 a.m.-11:35 a.m. | SSA13-05 | Room E451BIn this scientific presentation, researchers from Massachusetts General Hospital in Boston will discuss their successful use of CT perfusion imaging to monitor the response to sarcoma treatment. Both tumor size and density differences were visible after antiangiogenic therapy for soft-tissue sarcomas.

CT unnecessary in most blunt trauma admissions
Sunday, November 28 | 11:05 a.m.-11:15 a.m. | SSA05-03 | Room N227Blunt trauma patients admitted to emergency departments are routinely scanned with CT of the chest, abdomen, and pelvis. But are all those scans really necessary in the absence of serious signs of injury? No, say Noam Millo, MD, and colleagues from the University of Alberta in Edmonton.

Individualized contrast injection keeps up with triple-rule-out CT
Sunday, November 28 | 10:55 a.m.-11:05 a.m. | SSA04-02 | Room S404CDOutrunning the contrast bolus can be a real problem with state-of-the art CT equipment that scans the thorax in less than a second. But J. Michael Barraza and colleagues from the Medical University of South Carolina in Charleston found excellent results with a contrast injector equipped with an individualized patient-based contrast media injection algorithm.

Use of head CTA scans surges in Medicare patients
The use of CT angiography (CTA) for head and neck indications has gone through the roof in the past few years -- rising by more than 800% between 2002 and 2007 in the Medicare population, according to a new study in the November issue of the Journal of the American College of Radiology.

Access trumps sophistication in bid to bring CT to Africa
A new program called CT for Africa aims to address global disparities in access to healthcare by making advanced imaging technology such as CT available in developing countries. The firm that launched the program, GE Healthcare, is delivering low-cost CT units to areas that previously only had access to radiography.

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).

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.

Sagittal, coronal, and axial fused Tc-99m PYP-SPECT/CT images of a 93-year-old male at baseline and after two years of tafamidis 61 mg daily by mouth therapy. Tc-99m PYP images are shown in color and CT images are shown in grey scale. These images show a reduction in visual grade from an initial grade of 3 (myocardial uptake > rib uptake) to a follow-up grade of 1 (myocardial uptake < rib uptake). Quantitative metrics decreased significantly as well.
