Lung screening study finds value in CR temporal subtraction
Computed radiography (CR) with temporal subtraction has proved more accurate than CR alone or chest CR with double reading in a study from Japan. The observer performance trial used exams from a 12-year archive of mobile lung cancer screenings.

Survey tracks pace of cardiac PACS and CVIS integration
Hospitals are not just acquiring cardiac PACS and cardiovascular information systems (CVIS). More facilities are integrating images and data to give cardiologists a more convenient presentation of test results that factor into diagnosis and patient monitoring, according to a new report from IMV Medical Information Division.

Colored wristbands solve MR safety problem at Mayo Clinic
MRI personnel at the Mayo Clinic in Rochester, MN, have learned to look for teal-colored wristbands on patients administered minimal sedation during MRI scans. The colorful wristbands indicate that patients require a nurse's assessment to determine when it is safe for them to go home.

CAD boosts sensitivity of x-ray lung cancer screening
Applying computer-aided detection (CAD) to digital x-ray images can help radiologists identify significantly more small lung nodules in screening radiographs for lung cancer, according to a study of asymptomatic adults in China.

DR tomo reduces need for CT to confirm lung cancer
Pairing low-dose digital radiography (DR) tomosynthesis with conventional radiography eliminates the need for three of every four CT scans typically performed to confirm lung lesions previously suspected on chest radiography, according to a study from the University of Trieste in Italy.

An example of a typical BgRT plan: A) PET scan on diagnostic PET/CT and B) X1 PET-Linac for patient #15 with a PET avid rib metastasis with GTV size= 3.1 cc, PTV = GTV + 5mm, BTZ (biological tracking zone) = PTV + 5 mm, AC = 14.33 kBq/mL and NTS = 21.04. Red, magenta, and green contours represent GTV, PTV, and BTZ. C) Dose distribution and D) bounded-DVH of a BgRT plan are displayed for the same patient. The bounded Dose-Volume Histogram (DVH) models variations in BgRT delivery, encompassing fluctuation in target background signal variation, target localization and dose delivery uncertainties.

Saliency maps using Grad-CAM++ (E and H) show the model’s point of interest in chest radiographs (C and F) of patients with achalasia. The model’s point of interest is highlighted with red, yellow, and green. In both the upper and lower panels (E and H), the point of interest is located in a region around the upper esophagus that corresponds to an air esophagogram and/or air-fluid level in the esophagus in the barium esophagogram (D and G).

Diagnostic transverse ultrasound image of the left breast in a 64-year-old woman shows irregular hypoechoic nonparallel mass with indistinct margins corresponding to palpable finding, assessed as BI-RADS category 4. Both readers assessed mass as having associated echogenic rind with complete circumferential extent (arrowheads). Ultrasound-guided biopsy of mass yielded diagnosis of invasive ductal carcinoma (intermediate grade, luminal A molecular subtype, no lymphovascular invasion).
