In a 2015 articles in the Journal of Urology, Thompson reported multi-parametric MRI detection of significant prostate cancer had sensitivity of 96%, specificity of 36%, negative predictive value and positive predictive values of 92% and 52%; when PI-RADS was incorporated into a multivariate analysis (PSA, digital rectal exam, prostate volume ...
A study correlating MRI and surgical pathology specimens demonstrated a sensitivity of 59% and specificity of 84% in identifying cancer when T2-weighted, dynamic contrast enhanced, and diffusion-weighted imaging were used together. [10] Many prostate cancers missed by conventional biopsy are detectable by MRI-guided targeted biopsy. [11]
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
[8] [9] Infection after the biopsy procedure is a possible risk. [10] MRI guided techniques have improved the diagnostic accuracy of the procedure. [12] [13] Biopsies can be done through the rectum or perineum. [29] The biopsy technique includes factors such as needle angle and prostate mapping method. [30]

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.
A prostate tissue biopsy is a medical procedure in which a sample of tissue is taken from the prostate gland for diagnostic purposes. The prostate gland can be accessed through the perineum, the skin between the scrotum and anus.
MRI results can help distinguish those who have potentially dangerous tumors from those who do not. [26] A definitive diagnosis of prostate cancer requires a biopsy of the prostate. Prostate biopsies are typically taken by a needle passing through the rectum or perineum, guided by transrectal ultrasonography, MRI, or a combination of the two.
