PET/CT finds footing in breast, cervical, and ovarian carcinomaPET/CT continues to find new applications in detection and monitoring of breast, cervical, and ovarian carcinoma. An estimated 211,000 new cases of invasive breast carcinoma, with almost 41,000 deaths, are expected to occur in the U.S. during 2007. Breast carcinoma is the most frequently diagnosed malignancy in women and ranks second in terms of cancer deaths after lung cancer.

Improved Evaluation and Follow-up of Routine Diagnostic Oncology ExamsDiagnostic, staging and follow-up exams for tumors are among the most frequent CT exams performed in many radiology departments. For the University of Erlangen, oncology related imaging represents approximately 60% of the daily CT workload. To date, exams are read and evaluated in 2D, employing manual measurement and reporting of lesions.

MRS gains indications, but still fights for reimbursementTo paraphrase Mark Twain, reports of the death of diagnostic MR spectroscopy are greatly exaggerated. CPT 76390 is considered standard of care as an effective imaging technique for the diagnosis, treatment, and monitoring of patients with brain lesions by Cigna Healthcare, a respected healthcare provider,1 though declared "investigational" by Blue Shield, Anthem, and Medicare. Radiologists and other physicians are confused and annoyed by some insurers' refusal to reimburse for their MRS services.

Study finds huge variations in pediatric nuclear medicine dosingA survey of children’s imaging services has found a twofold variation in radiopharmaceutical doses administered during pediatric nuclear medicine exams. For some radiopharmaceuticals, the reported maximum activities varied by as much as a factor of 10, and minimum activities differed by as much as a factor of 20, suggesting the need for a consensus among nuclear physicians on appropriate doses for young patients.

Analysis teases out true value of outsourcing anytime readsThe need for nighttime coverage relief was the initial driver of commercially viable teleradiology. For several years, however, the local in-house radiology group gained no economic value for outsourcing its nighttime work, because its members had to reread the cases the next day to formally convert the reports to primary reads. The group also had to pay a premium for nighttime services.

Ovarian lesions pose diagnostic dilemmasThe main objective of imaging patients with symptoms suggestive of ovarian lesions is to distinguish benign findings from malignant disease. Masses can be characterized with a variety of noninvasive imaging techniques, including transabdominal and transvaginal ultrasound, CT, and MRI. Each of these modalities has its advantages and limitations.
