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 ...
The extent of cancer spread is assessed by MRI or PSMA scan – a positron emission tomography (PET) imaging technique where a radioactive label that binds the prostate protein prostate-specific membrane antigen is used to detect metastases distant from the prostate. [30] [24] CT scans may also be used, but are less able to detect spread ...
Prostate cancer is common, with almost 300,000 new diagnoses in the U.S. each year; one in every eight men is diagnosed with it in their lifetime. Prostate enlargement, how it affects men as they ...
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
Prostate cancer screening is the screening process used to detect undiagnosed prostate cancer in men without signs or symptoms. [1] [2] When abnormal prostate tissue or cancer is found early, it may be easier to treat and cure, but it is unclear if early detection reduces mortality rates. [2] Screening precedes a diagnosis and subsequent treatment.
Benign prostatic hyperplasia (BPH), also called prostate enlargement, is a noncancerous increase in size of the prostate gland. [1] Symptoms may include frequent urination , trouble starting to urinate, weak stream, inability to urinate , or loss of bladder control . [ 1 ]
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 technique has demonstrated higher accuracy than other modalities in assessing seminal vesicle invasion and extra-capsular extension (ECE) of prostate cancer (96% and 81% respectively). Endorectal coil MRI is useful for determining the extent of spread and local invasion of cancers of the prostate , rectum , and anus . [ 2 ]
