Hepatic inflammatory pseudotumor (IPT) is characterized by a well-circumscribed benign tumor mimicking or often mistaken for a malignant lesion. A 48-year-old male presented to the hospital with complaints of epigastric pain, with initial laboratory findings showing mildly elevated alkaline phosphatase (140 U/L) with normal AST, ALT, bilirubin, and lipase, a CD4 count of 384, and an HIV viral load of #x3e; 10 million copies. The total IgG level was elevated to 2,228 mg/dL (normal IgG4 level 114 mg/dL). Contrast-enhanced MRI of the abdomen showed heterogeneous mass-like infiltration in the right lobe of the liver measuring ...

We examined this relationship in a large population of patients in whom the coronary anatomy was defined by invasive coronary angiography. Methods We retrospectively extracted details on individuals undergoing MPI with single photon emission computed tomography (SPECT) who had coronary angiography within 12 months. A 17-segment model for native coronary anatomy and a 7-region model for myocardial perfusion were used with a dedicated matching algorithm. Results A total of 2564 patients were included, yielding a total of 6279 stenoses matched with 17 948 myocardial regions. From such a cohort, 151 (5.9%) patients had...

Conclusions: Current imaging cannot accurately characterize the functional status of the CVN or predict an assistive device benefit. Children who would have otherwise been denied a CI exhibited auditory responses after implantation. A CI should be considered in children with abnormal CVN. Furthermore, imaging acquisition protocols need standardization for clear temporal bone imaging.Audiol Neurotol 2018;23:48 –57

Radiology has always been at the forefront of technological advances in medicine. Although first conceptualized in 1979, multienergy computed tomography (CT) became practically feasible only recently, when technological limitations were addressed. The first multienergy CT scanner was released in 2006 and utilized two separate x-ray tubes offset by 90 °, which enabled simultaneously scanning at two different energy levels. This unique design allowed radiologists to exploit the differences in attenuation of various tissues within the body in order to identify their composition.

Dual-energy CT (DECT) is an emerging technology that has potential to enhance diagnostic performance and radiologists ’ confidence in the evaluation of thoracic malignancies. DECT clinical applications include characterization of solitary pulmonary nodule, lung masses and mediastinal tumors. DECT-derived iodine uptake quantification may assist in characterization of tumor differentiation and gene expression. The use DECT in oncology has potential to improve lung cancer staging, therapy planning, and assessment of response to therapy as well as detection of incidental pulmonary embolism.

Dual energy computed tomography is becoming increasingly widespread in clinical practice. It can expand on the traditional density-based data achievable with single energy computed tomography by adding novel applications to help reach a more accurate diagnosis. The implementation of this technology in cardiothoracic vascular imaging allows for improved image contrast, metal artifact reduction, generation of virtual unenhanced images, virtual calcium subtraction techniques, cardiac and pulmonary perfusion evaluation, and plaque characterization. The improved diagnostic performance afforded by dual energy computed tomography...

The added value and strength of dual energy computed tomography for the evaluation of oncologic patients revolve around the use of lower energy reconstructed images and iodine material density images. Lower keV simulated monoenergetic images optimize soft tissue tumor to nontumoral attenuation differences and increase contrast to noise ratios to improve lesion detection. Iodine material density images or maps are helpful from a qualitative standpoint for image interpretation because they result in improved detection and characterization of tumors and lymph node involvement, and from a quantitative assessment by enabling in...
