Adrenal Incidentaloma Triage With Single-Source (Fast-Kilovoltage Switch) Dual-Energy CT

Temporal Resolution Improvement in Single Source and Dual Source CT

Purpose: Recently a new method called TRIPICCS (Temporal Resolution Improved Prior Image Constrained Compressed Sensing) was proposed to improve the temporal resolution of a single source (SS) cardiac CT scan [1] (figures 1+2). This method aims at doubling the temporal resolution and at maintaining homogeneous temporal resolution independently of the location and the motion direction of a vesse...

A Rare Adrenal Incidentaloma: Adrenal Schwannoma

Adrenal schwannoma is an extremely uncommon cause of incidentaloma. It originates from neural sheath Schwann cells of the adrenal gland. We report the case of a left adrenal schwannoma incidentally discovered in a 32-year-old woman during examination of bloated feeling and stomach ache. The patient was incidentally found to have a left adrenal mass of 9 cm on abdominal ultrasonography. Computed...

Dual Energy Single Source Ct Coronary Perfusion Angiography – a Helpful Functional Adjunct to Anatomical Information

Temporal Resolution and Motion Artifacts in Dual-Source Cardiac CT and Single-Source CT with Iterative Reconstruction

The temporal resolution (TR) of an image has become an important property in computed tomography (CT) when examining organs whose motion can not be stopped for the duration of the CT scan, such as in cardiac CT. In this context, “higher TR” conventionally means that the raw data from which a given image was reconstructed was measured within a shorter time interval than the raw data of a similar...

Multi-Detector-Row CT Diagnosis of Adrenal Incidentaloma in Patients with Hepatocellular Carcinoma

We investigate the diagnostic reliability of differentiating between lipid-poor adrenal adenomas and metastatic adrenal tumors originating from hepatocellular carcinoma (HCC) using a routine dynamic CT protocol for liver imaging. Eighteen metastatic adrenal tumors originating from HCC and 13 lipid-poor adrenal adenomas were identified. Dynamic CT data were analyzed for CT attenuation of adrenal...
