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.

Principalele obiective ale acestui articol sunt: revizuirea tehnicii utilizate în evaluarea IRM multiparametrică în patologia prostatei, prezentarea şi ilustrarea principalelor aspecte IRM întâlnite în cancerul de prostată şi prezentarea rolului abordului multidisciplinar în diagnosticul şi managementul pacienţilor cu patologie tumorală prostatică.

Prostate prostate imaging techniques 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.

Multiparametric Magnetic Resonance Imaging in prostate cancer diagnosis: a must

Prostate specific antigen PSA bush al hindi prostatita primarily used in the 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. Detection localization — detection and characterization protocol. Staging protocol: tumor extension, presence of node and bone metastasis.

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 prostate imaging techniques 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.

Post-biopsy intraprostatic hemorrhagic spot hyperintense on T1FS wi, and hypointense T2 wiwhich can mimic a tumoral nodule arrow It is very important that the slices obtained on T2 wi, diffusion, dynamic T1 after gadolinium Gd injection have the same plane centeringslices number, slice thickness and identical interslice space for a correct and easy analysis.

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 prostate imaging techniques Figure 3 prostate imaging techniques Table 1.
