3PROSTATE MRI
DISCUSSION
With the rise in demand of the prostate MRI by the clinicians, imaging branches are
being tested to set up an imaging practice which will fulfil the latest criteria. By utilizing the
suggested multi-parametric method, image is created into three different sequences, which are T2
weighted, diffusion-weighted, and dynamic contrast-enhanced imaging. All sequence type has a
unique subset of artefacts that must be recognized when recording and excluded from the
scanning process. Diffusion-weighted MR imaging (DW-MRI) is a capable method that can
deliver together qualitative and quantitative data concerning the motion of water particles inside
the tissue, and can be provided in the present imaging procedures without a considerable rise in
the total analysis time (60-300 seconds), and does not need the management of exogenous
contrast material. Prostate cancer is the most common non-cutaneous cancer (Burton et al.,
2018). After the introduction of prostate-specific antigen (PSA) testing in the 1980s, there has
been a descending drift in cancer stage during the analysis. It is often believed that prostate
imaging comprises the use of a 3.0T MRI unit and multi-parametric MRI methods. Integrating
DW-MRI, MR spectroscopic imaging, dynamic contrast-enhanced MRI and in addition to
conventional T2-weighted images has shown an increase in the specificity for prostate cancer
recognition and localization.
Multiparametric MRI (mpMRI) has been an approved method for prostate lesion
identification with the help of vital sequences (Ahmed et al., 2016). In particular, Diffusion-
weighted magnetic resonance imaging (DWI) has demonstrated a converse correspondence to
tumour Gleason grade with the capability to differentiate Low-, medium- and high-risk prostate
cancer. DWI generally uses magnetization preparation gradients to sensitize the Nuclear
