Primary MRI Tech Job Duties and Daily Workflow
The daily routine of an MRI technologist is a highly structured, sequence of clinical and technical operations. No two days are identical, but every single patient encounter requires a meticulous, step-by-step workflow to ensure diagnostic accuracy and patient comfort.
The workflow begins long before the patient lies down on the scanner table. Here is how a typical daily routine unfolds:
- Reviewing Physician Orders: The technologist’s first responsibility is to carefully evaluate the incoming physician orders. This step ensures that the requested exam matches the patient’s clinical history and symptoms. Any discrepancy requires immediate clarification with the ordering physician or the reading radiologist.
- Reviewing Patient Medical History: Understanding the patient’s background is essential. Technologists review electronic medical records (EMR) to identify pre-existing conditions, past surgeries, and potential contraindications.
- Selecting and Verifying Protocols: Based on the clinical indication, the technologist selects the appropriate scanning protocol (such as a specific sequence set for a brain scan for Multiple Sclerosis, or a dynamic abdominal sequence).
- Preparing the Patient: This involves explaining the procedure in plain, reassuring language, answering questions, and helping the patient change into MR-safe scrubs or gowns.
- Patient Positioning and Coil Selection: Proper positioning is critical for both patient comfort and image quality. The technologist must select the correct receiver coil (e.g., head, knee, shoulder, or torso coil) and position it precisely over the target anatomy. They utilize cushions, pads, and immobilization devices to help the patient remain completely still throughout the scan.
- Operating the Scanner and Evaluating Quality: Once the scan begins, the technologist monitors the acquisition from the control console, evaluating each sequence in real time to check for patient motion, artifacts, and diagnostic completeness.

Patient Safety, Comfort, and Magnetic Field Screening Protocols
Operating a high-field-strength magnet (typically 1.5 Tesla or 3.0 Tesla) is a massive responsibility. Because the MRI magnet is always on, safety is the absolute highest priority within the Radiology department. The screening process is where safety actually happens, and the technologist serves as the primary gatekeeper.
Strict Screening Protocols
Every patient, family member, and healthcare worker must undergo a rigorous screening process before entering the magnet room (designated as Zone IV). The technologist must conduct detailed screening interviews to identify:
- Ferrous (magnetic) implants, shrapnel, or foreign bodies.
- Cardiac pacemakers, implantable cardioverter-defibrillators (ICDs), and neurostimulators.
- Cochlear implants or prosthetic heart valves.
- Metallic tattoos or permanent makeup, which can contain iron oxide pigments and present a thermal burn risk.
- Pregnancy status.
If an implant is present, the technologist must research the exact make and model of the device to determine if it is MR-Safe, MR-Conditional (requiring specific scanner settings), or MR-Unsafe.
Managing Patient Comfort and Anxiety
An MRI scanner can be an intimidating environment. The bore is narrow, and the gradient coils produce loud knocking and buzzing noises that can easily exceed 100 decibels. Technologists must manage patient psychological comfort by:
- Providing appropriate hearing protection (earplugs or specialized MR-safe headphones with music).
- Addressing claustrophobia through clear communication, breathing exercises, and constant reassurance via the intercom system.
- Offering panic buttons so patients can signal for immediate assistance if they feel overwhelmed.

Technical Skills, Equipment Operation, and Administrative Tasks
An MRI technologist is both a compassionate caregiver and a highly skilled technical specialist. Operating a computerized MRI console requires a solid foundation in imaging physics, cross-sectional anatomy, and clinical pathology.
Equipment Operation and Parameter Manipulation
Modern MRI scanners are highly customizable. Technologists do not simply push buttons; they actively manipulate scan parameters to optimize image quality. Key adjustments include:
- TR (Repetition Time) and TE (Echo Time): Controlling these timing parameters determines the contrast of the image (e.g., T1-weighted, T2-weighted, or Proton Density).
- FOV (Field of View) and Slice Thickness: Adjusting these parameters balances spatial resolution against the signal-to-noise ratio (SNR) and total scan time.
- Coil Selection: Choosing and placing the right surface or volume coils to maximize signal reception from the specific body part being imaged.
Contrast Media Administration
Many MRI exams require the use of intravenous contrast agents, such as gadolinium-based contrast media, to highlight vascular structures, tumors, or inflammation. Technologists are responsible for:
- Screening patients for renal function (reviewing eGFR and creatinine levels) to prevent complications like Nephrogenic Systemic Fibrosis (NSF).
- Establishing intravenous (IV) access.
- Loading and programming power injectors to deliver contrast at precise flow rates and volumes.
- Monitoring the patient closely during and after the injection for any signs of an adverse allergic reaction.
Administrative and Quality Control Responsibilities
Beyond direct clinical care, technologists must manage a variety of administrative and technical maintenance tasks to keep the department running smoothly:
- Quality Control (QC): Performing daily and weekly phantom scans to test scanner calibration, center frequency, and signal-to-noise ratio, logging the results to comply with regulatory standards.
- Information Systems: Entering patient data, tracking procedure codes, and managing billing charges in Radiology Information Systems (RIS), electronic medical records (EMR), and legacy platforms like AS400.
- PACS Management: Verifying, post-processing, and transferring completed diagnostic images to the Picture Archiving and Communication System (PACS) for radiologist review.
