MRI Scan Guide
Overview
A prostate MRI produces highly detailed images of the prostate gland and surrounding structures. It is the most accurate imaging method for detecting and characterizing prostate cancer, often using a multiparametric technique (mpMRI).
Prostate MRI is commonly used when PSA levels are elevated, before or after biopsy, for active surveillance of known prostate cancer, and for staging. Multiparametric MRI combines different imaging sequences to provide comprehensive information about the prostate.
The scan does not use radiation, is non-invasive, and most patients find it straightforward. No endorectal coil is needed with modern high-field scanners.
The procedure
You lie on your back on the scanner table with a body coil placed over your pelvis. The table slides into the scanner. Multiple imaging sequences are acquired, including T2-weighted images (for anatomy), diffusion-weighted images (for tissue cellularity), and dynamic contrast-enhanced images (for blood flow). These sequences together constitute a multiparametric MRI. The scan takes approximately 30 to 45 minutes.
Diagnostic value
Preparation
You may be asked to use a fleet enema 1 to 2 hours before the scan to clear the rectum.
Avoid ejaculation for 48 hours before the scan (this improves image quality).
No fasting is required unless specified.
Inform the clinic about any hip replacements or pelvic hardware.
Multiparametric prostate MRI findings are reported using the PI-RADS scoring system (Prostate Imaging Reporting and Data System). Each lesion is scored from 1 to 5: PI-RADS 1 and 2 are very likely benign, PI-RADS 3 is indeterminate, and PI-RADS 4 and 5 are likely clinically significant cancer. This standardized system helps your urologist decide whether biopsy is needed.
Understanding your results
Every Mira scan comes with two reports. A medical report from a radiologist for your doctor, and a miraclarity report for you. The miraclarity report explains your prostate MRI findings in straightforward language with visual guides, severity indicators, and recommended next steps.
No jargon. No waiting for another appointment just to understand what your scan found. miraclarity is included free with every scan.

Current guidelines recommend prostate MRI before biopsy in many cases. MRI can help identify suspicious areas and guide targeted biopsy, potentially avoiding unnecessary procedures.
A typical prostate MRI takes 30 to 45 minutes.
With modern high-field MRI scanners (1.5T and 3T), an endorectal coil is generally not required. The scan is performed with an external body coil only.
A knee MRI uses magnetic resonance imaging to produce detailed cross-sectional images of the knee joint. Unlike X-rays, which show only bones, MRI reveals soft tissues including ligaments, cartilage, tendons, and the meniscus. This makes it the primary diagnostic tool for knee injuries and conditions.
A brain MRI produces highly detailed images of the brain, brainstem, and surrounding structures. It is the preferred imaging method for evaluating neurological symptoms because it provides superior soft tissue contrast compared to CT and does not use ionizing radiation.
A lumbar spine MRI produces detailed images of the lower back, including the vertebrae, intervertebral discs, spinal cord, nerve roots, and surrounding soft tissues. It is the most accurate non-invasive method for diagnosing causes of lower back pain.
A shoulder MRI provides highly detailed images of the rotator cuff, labrum, cartilage, tendons, ligaments, and bones of the shoulder joint. It is the most reliable non-invasive method for diagnosing shoulder injuries.
