Mri safety

FDA

According to the Alert, the Food and Drug Administration (FDA) has received nearly 400 reports of MRI-related accidents over the past decade. More than 70 percent of accidents were burns, while 10 percent of injuries occurred when metal objects such as ink pens, cleaning equipment and oxygen canisters have become "missiles" when pulled into the magnetic field of the scanner.

Mri safety zones

MRI safety zones

  • Zone 1: General Public: Front reception area

  • Zone 2: Unscreened MRI patients: Front reception area, where unscreened MRI patients wait for their examinations.

  • Zone 3: Screened MRI patients, visitors, and personnel: Screened by a technologist, technologist aide, or MRI nurse prior to entering this zone. Zone is secured by a door which only MRI staff members can let patients and visitors through.

  • Zone 4: Screened MRI patients under constant direct supervision of trained MRI personnel: Is the magnet room. All patients, escorts, and visitors must pass the MRI screening. Anyone who enters Zone 4 must be escorted by an MRI Technologist, MRI Nurse or Technologist Aide.

Mri safety

  • Before undergoing an MR procedure must remove:

    • all removable metallic personal belongings and devices on or in them (e.g., watches, jewelry, pagers, cell phones, body piercings [if removable], contraceptive diaphragms, metallic drug delivery patches, cosmetics containing metallic particles [such as eye make-up], and clothing items that may contain metallic fasteners, hooks, zippers, loose metallic components, or metallic threads).

    • Patients are required to wear a gown without metal fasteners/hospital gowns without snaps.

Oxygen tanks

Oxygen Tanks

GREEN oxygen tanks are NOTMRI compatible

NEVERbring a GREEN tank into a MRI room or near the MRI machine under ANY circumstance.

SILVER oxygen tanks ARE MRI compatible


Equipment for mri

Equipment for MRI

All equipment for MRI is labeled “MRI Compatible”. This SPECIFIC equipment can go into the MRI room. The technologist will decide what can go into the room.


Burns

What is nephrogenic systemic fibrosis nsf

What is Nephrogenic systemic fibrosis (NSF)?

.


Nephrogenic systemic fibrosis

Nephrogenic systemic fibrosis

  • Rare and serious syndrome that involves fibrosis of skin, joints, eyes, and internal organs.

  • The first cases were identified in 1997.

  • Cause is not fully understood.

  • Evidence to suggest that it is associated with exposure to gadolinium (with gadolinium-based MRI contrast agents being frequently used as contrast agents for magnetic resonance imaging) in patients with severe kidney failure.


How can we help prevent this disease

How can we help prevent this disease?

Asking these patients the following questions both when scheduling and screening patients.


Mri safety

ACR recommendationsNew recommendations for screening These are the questions which need to be asked to EVERY patient.

  • Patients over the age of 60

  • History of renal disease (including one kidney, kidney transplant, kidney tumor or kidney mass).

  • History of “Hypertension” (if patient is undergoing treatment for hypertension).

  • History of diabetes mellitus: type I and type II

  • If the patient receiving dialysis? Proceed with the Policy : MRI Exams for DIALYSIS Patients.

  • Patients in Acute Renal Failure/Insufficiency, peritoneal dialysis or severe liver failure/pre/post liver transplant will NOT receive a contrast MRI regardless of GFR value. These patients will be decided on a case by case basis by the Radiologist.
