Accuracy of Non-Enhanced CT in Detecting Early Ischemic Edema Using Frequency Selective Non-Linear Blending.

Autor: Georg Bier, Malte N Bongers, Hendrik Ditt, Benjamin Bender, Ulrike Ernemann, Marius Horger

Publikováno v: PLoS ONE, Vol 11, Iss 1, p e0147378 (2016)

PURPOSE:Ischemic brain edema is subtle and hard to detect by computed tomography within the first hours of stroke onset. We hypothesize that non-enhanced CT (NECT) post-processing with frequency-selective non-linear blending ("best contrast"/BC) incr

Autor: Moritz T. Winkelmann, Florian Hagen, Kerstin Artzner, Malte N. Bongers, Christoph Artzner

Publikováno v: Diagnostics, Vol 12, Iss 10, p 2542 (2022)

The purpose of this study was to evaluate the potential of dual-energy CT (DECT) with virtual unenhanced imaging (VNC) and iodine maps (IM) to differentiate between intraperitoneal hematomas (IH) and bowel structures (BS) compared to linearly blended

Case Report: MRI, CEUS, and CT Imaging Features of Metanephric Adenoma with Histopathological Correlation and Literature Review

Autor: Georg Gohla, Malte N. Bongers, Sascha Kaufmann, Mareen S. Kraus

Publikováno v: Diagnostics, Vol 12, Iss 9, p 2071 (2022)

The metanephric adenoma is an extremely rare, benign, embryonal-epithelial neoplasm of the kidney and has a good prognosis with appropriate treatment. It can present at any age and is often asymptomatic. Histologically, the lesion is well established
