CAD for chest x-ray detects overlooked subtle lung cancer
Computer-aided detection (CAD) software found nearly half of all lung tumors missed by radiologists on their original interpretation of images, according to a study by University of Maryland researchers that's being published in the July issue of Radiology.

Adding RFA to chemo better treats colorectal liver metastases
Patients with unresectable colorectal liver metastases who receive radiofrequency ablation (RFA) with chemotherapy treatment have longer progression-free survival than patients treated with chemotherapy alone, according to a new study by Dutch researchers.

Dose can be reduced by 75% in pediatric chest CT exams
The radiation dose of pediatric MDCT exams can be reduced by as much as 75% without compromising the ability to detect small lung nodules in young children, according to a study published in the July issue of Academic Radiology.

Brachytherapy: The gold standard for low-risk prostate cancer patients?
More than 1,000 men treated for low- and intermediate-risk prostate cancer with low-dose brachytherapy have had excellent five- and seven-year outcomes, according to Canadian researchers. They believe the results of this large population-based study validate the use of brachytherapy as a new reference gold-standard treatment.

Brachytherapy outcomes equal bladder removal for some cancer patients
A study that compared patients in the Netherlands who received brachytherapy to those who qualified for this treatment but had a radical cystectomy instead revealed comparable survival outcomes five years after treatment.

PACS at imaging centers pose challenges for administrators
CHARLOTTE, NC - PACS administrators who work in imaging centers don't have the same level of financial resources or staff as their hospital counterparts. But by networking with those who can provide information and/or professional support, including counterparts at competitive healthcare facilities, the job of managing imaging informatics activities can become more successful and less stressful.

Critical results software -- it's cheaper than settling lawsuits
CHARLOTTE, NC - Many imaging facilities might dismiss the new generation of IT software for managing critical test results as an expensive and unnecessary hassle. But such a purchase could be far cheaper than settling the lawsuits that could result if critical radiology results aren't received by the correct recipient.

Digital mammography transition: The hidden issues
The combination of foresight and the hindsight of others can make the process of new technology implementation easier. So when Dr. Barbara Monsees described the issues she discovered when converting to digital mammography, breast imagers sat up and took notice at the Society of Breast Imaging's postgraduate course held last month.

Color-coded CT protocols help reduce pediatric radiation dose
Radiologists at Massachusetts General Hospital were able to reduce pediatric CT radiation dose by up to 90% through a system of color-coded exam protocols customized to individual patients, according to an article published in the July issue of Radiology.

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.
