No study to test the feasibility and prognostic value of the number of primary tumors, the number of positive lymph nodes, and the total number of tumors in the whole body as tumor burden measurements on FDG PET/CT imaging has been reported. ⋯ Measuring the number of tumors on FDG PET imaging is easy to perform with minimal inter-observer variability. The total number of tumors and number of nodal metastases, as metabolic tumor burden measurements in 18F-FDG PET/CT, are prognostic markers independent of clinical stage, age, gender, and SUV measurement in non-surgical patients with NSCLC.

The decreased portal blood flow and the potential decrease in arterial nutrient hepatic blood flow after creation of a transjugular intrahepatic portosystemic shunt (TIPS) makes the treatment of hepatocellular carcinoma (HCC) challenging. ⋯ Selective TACE may be safe and effective for the palliative treatment of HCC in patients with TIPS. Late tumor stage ( ≥III) was poor prognostic factor for determining the patient survival period after post-TIPS TACE.

Further development established hand-carried ultrasound (HCU) imagers in daily clinical workflow providing several advantages such as fast bedside availability and prompt diagnosis. ⋯ Due to its ease of use and its high diagnostic yield HCU systems of the latest generation constitute a helpful technique for the primary assessment of PE.

As diffusion-weighted imaging (DWI) is routinely incorporated into the standard clinical protocol, it is clinically relevant to determine whether DWI after gadoxetic acid is comparable to pre-contrast DWI, with regard to the detection and characterization of focal liver lesions. ⋯ Gadoxetic acid-enhanced DWI showed comparable diagnostic capability to unenhanced DWI for the detection and characterization of small focal hepatic lesions.

With the widespread use of PET/CT, incidental hypermetabolic foci unrelated to the known malignancy have been described with increasing frequency. ⋯ Incidental focal 18F-FDG uptake in the breast as detected by PET/CT was indicative of malignancy in 45% of patients. Both mean SUV(max) and diameter were greater for malignant than benign lesions.
