“…Diffusion-weighted images using 1.5 T without the use of an endo-rectal coil was limited by the signal-to-noise ratio and produced noisy ADC images. However, the use of an external phase-coil array at 3T seems to yield image quality that is equivalent to that obtained with an endo-rectal coil at 1.5 T. 48 …”

In this article, we review the clinical applications of diffusion MR imaging in the radiotherapy treatment of several key clinical sites, including those of the CNS, the head and neck, the prostate and cervix. Diffusion-weighted MRI (DWI) is an imaging technique that is rapidly gaining widespread acceptance due to its ease and wide availability. DWI measures the mobility of water within tissue at the cellular level without the need of any exogenous contrast agent. For radiotherapy treatment planning, DWI improves upon conventional imaging techniques, by better characterization of tumor tissue properties required for tumor grading, diagnosis and target volume delineation. Because diffusion weighted MRI is also a sensitive marker for alterations in tumor cellularity, it has potential clinical applications in the early assessment of treatment response following radiation therapy.

“…That is further the case for air that processes through the rectum during the examination. Nevertheless, studies at 1.5 Tesla found that image quality of prostate MRI without ERC to be equal to those with ERC without increased motion artefacts [5,12,13] . A few studies assessed the additional value of the use of an ERC for prostate MRI at 3.0 Tesla.…”

“…Consequently, they suggested waiving of spasmolytic drug administration. At present, MRI of the prostate at 3.0 Tesla is becoming the state-of-the art examination, because the increased field strength at 3.0 Tesla potentially improves image quality by increased SNR [4,5] . Nevertheless, non-significant artefacts due to peristaltic bowel motion on 1.5 Tesla MR imaging may become more exaggerated on 3.0 Tesla MR imaging and result in reduced image quality.…”

AIM:To evaluate the value of administration of hyoscine-N-butyl-bromide (HBB) for image quality magnetic resonance imaging (MRI) of the prostate. METHODS:Seventy patients were retrospectively included in the study. Thirty-five patients were examined with administration of 40 milligrams of HBB (Buscopan ® ; Boehringer, Ingelheim, Germany); 35 patients were examined without HBB. A multiparametric MRI protocol was performed on a 3.0 Tesla scanner without using an endorectal coil. The following criteria were evaluated independently by two experienced radiologists on a five-point Likert scale: anatomical details (delineation between peripheral and transitional zone of the prostate, visualisation of the capsule, depiction of the neurovascular bundles); visualisation of lymph nodes; motion related artefacts; and overall image quality. RESULTS:Comparison of anatomical details between the two cohorts showed no statistically significant difference (3.9 ± 0.7 vs 4.0 ± 0.9, P = 0.54, and 3.8 ± 0.7 vs 4.2 ± 0.6, P = 0.07) for both readers. There was no significant advantage regarding depiction of local and iliac lymph nodes (3.9 ± 0.6 vs 4.2 ± 0.6, P = 0.07, and 3.8 ± 0.9 vs 4.1 ± 0.8, P = 0.19). Motion artefacts were rated as "none" to "few" in both groups and showed no statistical difference (2.3 ± 1.0 vs 1.9 ± 0.9, P = 0.19, and 2.3 ± 1.1 vs 1.9 ± 0.7, P = 0.22). Overall image quality was rated "good" in average for both cohorts without significant difference (4.0 ± 0.6 vs 4.0 ± 0.9, P = 0.78, and 3.8 ± 0.8 vs 4.2 ± 0.6, P = 0.09). CONCLUSION:The results demonstrated no significant effect of HBB administration on image quality. The study suggests that use of HBB is not mandatory for MRI of the prostate at 3.0 Tesla.

“…Using an external phased array coil at 3 T Sosna et al [70] found prostate prediction to be similar to the use of an endorectal coil at 1.5 T. Fütterer et al [71] reported initial experience of endorectal coil at 3 T. The signal-to-noise ratio at 3 T was superior to that at 1.5 T, and this increased the spatial resolution of the images and improved the spectral resolution of MRSI. A more detailed subsequent report from this group [72] has claimed high accuracy for staging prostate cancer with 3-T MRI.…”

Contemporary issues in the diagnosis of prostate cancer for the radiologist

Prostate cancer diagnostic techniques have improved considerably in recent years, but they must yet be optimised to ensure cancer detection at a potentially curable stage. Arrangements for prostate biopsy vary throughout Europe, and prostate biopsy may be undertaken by urologists or radiologists. This review discusses current issues relevant for radiologists involved in the detection of early prostate cancer. Prostate biopsy should be based on a systematic approach involving 8-12 cores obtained with peri-prostatic infiltration of local anaesthetic. Quality issues being considered by the United Kingdom Prostate Cancer Risk Management Programme are discussed.
