Transurethral MR-Thermometry Guided Ultrasound Ablation of the Prostate – The Heidelberg Experience During Phase I of the TULSA-PRO Device Trial

This article describes a novel, MRI-guided, minimally-invasive method to safely ablate target benign and malignant prostate tissue with millimeter accuracy and precision. Real-time MR thermometry performed during transurethral ultrasound delivery enables active feedback control of the thermal volume, with high success in the ablation of the target tissue. [...]

MR-Guided Biopsies of the Prostate in Supine Patient Position

The article shows that targeted biopsies of the prostate under direct MRI-guidance are a reasonable complement to ultrasound biopsy techniques. The presented cases show that exact targeting of the most suspicious portion of a tumor is crucial for correct classification and consequently best therapy decisions. Especially in case of relatively small lesions, direct MR-guidance has clear advantages over fusion techniques. [...]

First Clinical Experiences with Simultaneous Multi-Slice Accelerated Diffusion-Weighted Imaging Throughout the Body

Dr. Valentin Tissot (CHRU, Brest, France) presents cases throughout the whole body that demonstrate that Simultaneous Multi-Slice (SMS) helps to accelerate diffusion-weighted imaging in almost all clinical cases where DWI is commonly applied. Robust results and good image quality can be achieved with an SMS factor of 2, which allows one to achieve near 2-fold acceleration. He also shows that ADC values are highly reproducible between the conventional and the accelerated technique. [...]

Prostatic sarcoma

        Clinical History: 25-year old man with dysuria for 3 weeks   Diagnosis: Prostatic sarcoma   MR Technique: Prostatic imaging was performed on a 3T MR system. (A) Sagittal T2-weighted TSE (TR/TE 7500/104ms), (B) coronal T2-weighted TSE (TR/TE 7354/104ms), and (C) axial T2-weighted TSE (TR/TE 7440/101) were acquired prior to the administration […] [...]

Prostate carcinoma

This is a 70 yr old man who presented with change in his PSA levels. It was 4.3 in 2007 and 7.13 in 2010. He was asymptomatic. A biopsy showed a Gleason score of 9 on the right and prostate intraepithelial neoplasia on the left. Both bone scan and CT did not show metastasis. [...]

Assessment of Tumor Extension and Improved Localization for Planning and Nerve Sparing Radical Prostatectomy

The potential of state-of-the-art MRI at 3 T, in prostate imaging without the use of an endorectal coil, is discussed in this article. Two clinical cases are presented, with MRI in each instance able to improve both therapy planning and surgical outcome. [...]
