Pictorial Essay: Pulmonary Imaging for Children

Especially in children with oncologic diseases that can be treated curatively, MRI can be used for the thoracic staging of the axillary, hilar, and mediastinal lymph nodes and to assess pulmonary metastases. The pictorial essay presents 5 cases. [...]

Cerebral Magnetic Resonance Spectroscopy at 1.5T and 3T

MR spectroscopy is a powerful technique that adds metabolic information to routine MRI brain examinations. Through four cases, this article provides tips for performing cerebral MRS. Examples of additional information using this technique include differentiating cerebral neoplasms from abscesses and distinguishing solitary primary cerebral neoplasms from solitary cerebral metastatic deposits. [...]

How Breast MRI Changed the Operative Management

MR diffusion-weighted imaging (DWI) is no longer just for brain applications. Whole body DWI is becoming a standard application in routine imaging. Whole body DWI has become as valuable as T2 contrast in tumor imaging and it allows characterization of tissue properties. This article provides responses to some of the more frequently asked questions including the background, application, and interpretation of whole body DWI and its calculated Apparent Diffusion Coefficient (ADC) images. [...]

T1 SPACE for Improved Detection of Brain Metastases

T1 SPACE provides in a reasonable scan time a high resolution 3D acquisition of the brain, with improved detection of brain metastases when compared to MP-RAGE, and is advocated as the scan of choice at 3 T [...]

Whole-Body MRI for Accurate Assessment of Tumor Load of Bone Metastases Originating from Breast Carcinoma

With breast carcinoma, detection of metastases and estimation of tumor load is of high relevance for patient-individualized therapy regimes. This article presents two cases that show the advantages of MRI for imaging bone metastases originating from breast cancer. In both cases, there was the high clinical suspicion of tumor recurrence with metastastic spread. The patients underwent therefore combined whole- body 18F FDG PET/CT and whole-body MRI for tumor staging with special focus on the brain, liver and bone marrow. [...]

Case Reports: Tumor Detection by Diffusion-Weighted MRI and ADC-Mapping with Correlation to PET/CT Results

Early and accurate estimation of metastatic spread is essential for a patient-adapted, efficient therapy regime. In this context, whole-body and multi-step MRI have already helped to improve the diagnostic accuracy of staging examinations. As a further step, it is known that cancer is also often characterized by higher cellularity and therefore restriction of water diffusion. Diffusion-weighted imaging (DWI) with high b-values has therefore been applied to image metastases in order to help improve the diagnostic accuracy of MRI. The working-group of Schlemmer et al., Department of Radiology, University of Tuebingen, Germany, have compared the findings with results of 18F-FDG PET/CT exams. [...]

Case Report: Metastases from Neuroendocrine Carcinoma: Value of Diffusion-Weighted MR Imaging Compared to 68Ga-DOTATOC PET-CT

Neuroendocrine tumors may be challenging to diagnose. Diffusion-weighted MR imaging (DWI) plays an important role in the accurate detection of liver lesions, which may be occult onconventional MRI and especially CT. In the presented case, the suspicion of diffuse hepatic spread is also supported by the additionally performed 68Ga-DOTATOC PET. The article shows, that DWI […] [...]
