CT experts grapple with rising concerns about radiation dose
LAS VEGAS - Finding ways to handle rising concerns over radiation dose from CT scanning was the subject of a series of presentations Tuesday at Stanford University's International Symposium on Multidetector-Row CT. While several of CT's leading experts expressed frustration about the level of misinformation in the lay press on radiation dose, they acknowledged that more needs to be done to reduce dose to the lowest possible levels.

Salaries fell for radiologists, RTs in 2007, SalaryScan survey says
Radiologists and radiologic technologists (RTs) enjoyed a rising tide of prosperity in recent years as salaries grew steadily in an era of chronic personnel shortages. The gravy train appears to be over, however, as salaries for radiologists and RTs fell in 2007, according to the latest data from AuntMinnie.com's 2008 SalaryScan survey.

CT planning eliminates need for urethrography in prostate
Radiation therapy planning based on 3D CT has revolutionized radiation oncology, and researchers from the University of Texas Health Science Center believe they've found another benefit: the elimination of retrograde urethrography when planning treatment for prostate cancer. Their study results were published in the May 1 issue of the International Journal of Radiation Oncology, Biology, Physics.

Study examines reasons for CR image rejections
A new research study is shedding light on why computed radiography (CR) images are rejected for image-quality reasons. A U.S. group found that while new software tools make it easier to track CR rejects, additional quality-control training is recommended before imaging facilities implement programs for reject analysis.

Active thyroid surveillance effective, beneficial for older patients
A 58-year-old woman was diagnosed with ER-positive (Allred score 8) ILC in her right breast. Ultrasound and MRI found prominent lymph nodes in right axillary level I area, diagnosed as metastasis on ultrasound-guided fine-needle aspiration. F-18 FES-PET/CT showed a positive mass in right breast (white arrow; SUVmax, 5.6) and multiple F-18 FES–positive lymph nodes in right axillary level I, II, and II/III junction areas (red arrows; SUVmax, up to 12.2). In addition, a small F-18 FES-positive lymph node was observed in the right second internal mammary area (red circles; SUVmax, 1.8). However, biopsy could not be performed because it was too small and not visible on ultrasound; the clinician decided to include internal mammary lymph node in treatment field for adjuvant radiotherapy. The patient underwent lumpectomy with ALN dissection, with five metastases being identified in 13 lymph nodes dissected, and is scheduled to receive adjuvant chemotherapy, radiotherapy, and endocrine therapy.

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.

Dynamic PET/CT and pathologic images for a 66-year-old male participant. (A) Axial dynamic PET/CT image acquired during intravenous administration of Ga-68 PSMA-11 demonstrates the hypermetabolic primary prostatic tumor. The right-sided portion of the lesion used for volume of interest (VOI) analysis is outlined in pink, reflecting the margins seen on a prior T2-weighted MRI scan. Tumor radiotracer uptake extends across midline into the left anterior apex (*). (B) Axial dynamic PET/CT image acquired during selective right prostatic arterial administration of Ga-68 PSMA-11 demonstrates intense radiotracer uptake in the VOI outlined in pink. There is comparatively minimal uptake in the unperfused left-sided portion of the tumor (*). The arterial sheath and catheters in the right groin are partially visualized (arrow). (C) Photomicrograph (hematoxylin-eosin stain; unmagnified) of the prostatic apex after radical prostatectomy. The midline (dotted line) and dominant tumor margins (solid line) are shown. Small additional areas of carcinoma (■) without T2-weighted MRI correlates were also identified at pathologic examination.
