Clinical and imaging features of myeloid sarcoma: a German multicenter study.

Background: Myeloid sarcoma (MS), also known as chloroma, is an extramedullary manifestation of malignant primitive myeloid cells. Previously, only small studies investigated clinical and imaging features of MS. The purpose of this study was to elucidate clinical and imaging features of MS based upon a multicenter patient sample.

Cardiovascular findings on computed tomography in patients with unclear finding situation and trauma of unknown origin.

Incidental cardiovascular findings are common and can be found in up to 70% of patients. Previously, several reports about incidental findings (IFs) on whole body computed tomography (CT) were published. However, no previous study investigated cardiovascular IFs in patients with unclear finding situation and trauma of unknown origin on whole body CT.

Renal incidental findings on computed tomography: Frequency and distribution in a large non selected cohort.

Renal incidental findings (IFs) are common. However, previous reports investigated renal IFs were limited to patient selection. The purpose of this study was to estimate the prevalence and distribution of all renal IFs on computed tomography (CT) in a large patient collective.

Radiological findings on irradiation-CT in patients with non metastatic breast cancer.

Objective: The aim of this study was to evaluate the number of incidental findings on native CT treatment-planning scans for radiation in breast cancer patients.

Methods: The treatment-planning scans of 382 patients with non-metastatic breast cancer were retrospectively analyzed for additional findings. The planning scan area covered the entire thorax and the upper part of the abdomen.

ADC Histogram Analysis of Cervical Cancer Aids Detecting Lymphatic Metastases-a Preliminary Study.

Purpose: Apparent diffusion coefficient (ADC) histogram analysis has been used to some extent in cervical cancer (CC) to distinguish between low-grade and high-grade tumors. Although this differentiation is undoubtedly helpful, it would be even more crucial in the presurgical setting to determine whether a tumor already gained the potential to metastasize via the lymphatic system. So far, no studies investigated the potential of 3T ADC histogram analysis in CC to differentiate between nodal-positive and nodal-negative entities.
