Details drive service contract negotiations
SAN ANTONIO - A well-negotiated service contract can ensure that a modality is up and running in a timely and cost-efficient manner, while a poorly bargained service contract can impact a practice's referrals and carve large bites out of its bottom line, according to a presentation at the American Healthcare Radiology Administrators (AHRA) annual meeting.

Diagnostic imaging's future: Bigger than radiology
SAN ANTONIO - No one can argue that the volume of diagnostic imaging hasn't increased exponentially over the past decade. And by all accounts, usage will continue to increase as advanced imaging applications enable adoption of less invasive, more precise therapies, according to a presentation at the American Healthcare Radiology Administrators (AHRA) annual meeting.

IT governance in healthcare still evolving
In theory, and in practice in most industries, the chief information officer (CIO) is accountable for directing the information, data integrity, and information service functions of the enterprise. But in U.S. healthcare, the majority of CIOs do not govern all information technology (IT) resources at their institutions, according to results from a recent survey.

Turf sharing: Rads and cards in joint venture imaging
Although turf wars over medical imaging have become commonplace between radiologists and other clinical specialties in the U.S., some cardiology and radiology groups have abandoned the battle in order to form mutually beneficial joint venture cardiac imaging centers.

Pinhole SPECT shows promise for arthritis imaging
Multipinhole SPECT has long been used for preclinical animal imaging. But in the past few years, the technique has been introduced into the clinical setting, with prospective studies performed in parathyroid imaging, scintimammography, and ankle imaging. And now multipinhole SPECT shows promise in arthritis imaging as well, according to initial study findings from researchers in Germany.

3D navigation holds promise for image overload
The evolution of modalities used in the practice of radiology is fast producing a daily volume of images that threatens to overload the capacity of interpreting radiologists. But strategies for handling the increased workflow, such as the use of volumetric navigation, continue to evolve as well, according to a presentation at the Society for Computer Applications in Radiology (SCAR) meeting.

PET/CT provides cost-savings for NSCLC radiotherapy
PET/CT technology has been demonstrating superior diagnostic and staging capabilities for various malignancies in scientific studies. But the technology comes at a steep price point, and models for its economic efficiencies are still being created. However, researchers from Canada have found PET/CT to be cost-effective in radiation therapy planning for non-small cell lung cancer (NSCLC).

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.

Representative examples of visual TAC categories, assessed on chest CT in asymptomatic individuals undergoing general health screening (blue indicates segmented TAC at level of aortic arch). Axial (A) and sagittal volume-rendered (B) images in 42-year-old patient. AI-based quantification yielded TAC volume of 101 mm3 and TAC Agatston score of 105. Examination was assessed as showing visually mild TAC. Axial (C) and sagittal volume-rendered (D) images in 57-year-old patient. AI-based quantification yielded TAC volume of 834 mm3 and TAC Agatston score of 993. Examination was assessed as showing visually moderate TAC. Axial (E) and sagittal volume-rendered (F) images in 65-year-old patient. AI-based quantification yielded TAC volume of 4872 mm3 and TAC Agatston score of 5848. Examination was assessed as showing visually severe TAC. Images and caption courtesy of the AJR.
