The main objectives of this article are: to review the multiparametric MRI assessment technique used in prostate pathology, to list and illustrate the most common MRI features in prostate cancer, and to present the role of the multidisciplinary team in the diagnosis and management of patients with prostate tumoral pathology. Keywords prostate cancer, multiparametric MRI, multidisciplinarity Rezumat Cancerul de prostată reprezintă o importantă problemă de sănătate publică.

Imagistica prin rezonanţă magnetică IRM este cea mai bună modalitate de evaluare a prostatei şi de a diagnostica cancerul de prostată, mai ales în cazurile în care tumora este voluminoasă şi agresivă.

Introduction Epidemiology. Prostate cancer is the most common solid neoplasm in Europe and the second leading cause of male cancer deaths in USA and UK. Age is the most important risk factor Allmost all prostate cancers are adenocarcinomas.

Gleason score grade corresponds to a well differentiated prostatic tumor; grade is a moderately differentiated tumor, and signifies a poorly differentiated prostatic cancer 3. Prognostic indicators. TNM stage is the most important prognostic variable.

Prostate specific antigen PSA is primarily used in prostate volume normal range radiology diagnosis and detection of disease recurrence. High levels is correlated with advanced TNM stage at diagnosis 3. Indications of MRI evaluation in prostate cancer: 1.

Specificații

Detection localization — detection and characterization protocol. Staging protocol: tumor extension, presence of node and bone metastasis. Follow-up of a known prostatic tumor. Recurrences after treatment. A scale from 1 to 5, stratifying a focal prostatic abnormality according to the MRI findings, obtained with different MRI sequences, improves the reproducibility of radiologists reports and the communication with referring physicians Other sequences and technical requirements.

The prostate and seminal vesicles must be covered entirely slice thickness: 3 mm. Imaging, parallel to the prostate, perpendicular to the rectal face of the prostate, or oblique into the seminal vesicles plane are essential to evaluate extraprostatic extension Figure 1.

Different publications and studies regarding the correlation between ADC value on diffusion-weighted MR imaging and the Gleason score in prostate cancer have demonstrated that ADC values are lower in aggressive PC and correlated with the Gleason score Prostate cancer located in the PZ corresponds to an area of low signal intensity Figure 3 and Table 1.

The analysis of pelvic and retroperitoneal lymph nodes is obligatory. Abnormal lymph nodes on MRI take into account the size, morphology, shape, and the enhancement pattern.

Article Introduction Colorectal cancer CRC is the third most common cancer in men and the second most common in women. Although screening, addressability and increased awareness have augmented the number of cases in the non-metastatic setting, approximately one in four individuals with CRC will be diagnosed in stage IV. Additionally, because this improvement in survival has also been associated with substantial health care financial burden, appropriate selection of patients for specific treatments is of utmost importance. Currently, there are several biomarkers that help clinicians in making the optimal treatment decision: KRAS, NRAS, BRAF mutations, human epidermal growth factor receptor 2 HER2 amplification and microsatellite instability MSI or mismatch repair MMRthey all play a significant role in the process, facilitating selection of the right treatment for the right patient.
