What is the difference between MRI Sequences and MRI series?

In MRI (Magnetic Resonance Imaging), sequences and series refer to the different parameters and techniques used to acquire images of the body's internal structures. TeleradiologyHub has worked with thousands of MRI, CT, and X-ray teleradiology clients, and these questions are frequently asked by internal and external stakeholders. The TeleradiologyHub MRI second opinion team explains these concepts well for its second opinion seekers.

Patient View: Chronology of events during the MRI Scan

When do you go to the diagnostic center? After being referred by your local doctor or GP? Right?
Let's take a case. Your GP has asked for MRI report on your brain. GP writes it on piece of paper or tell orally. You then either search the diagnostic center online (like on portals TeleradiologyHub) or go as per advice from GP.  You then give that paper to the radiologist or their technician after reading the GP's advice. They prepare a protocol and ask you to wait. Once the MRI procedure starts, it can take 1-2 hours depending on the body part and contrast. After the MRI procedure is conducted, you are asked to wait for the report and DICOM images. Once you get the images, confusion can set in. You might find that the images don't open on your mobile or computer directly, and there are thousands of images. If you're able to find DICOM viewer software, you may struggle to understand what DICOM series and DICOM sequence mean.

MRI Series Vs MRI Sequence

A sequence in MRI refers to a specific combination of parameters that determines how the MRI machine generates the images.  An MRI sequence is a number of radiofrequency pulses and gradients that result in a set of images with a particular appearance. These parameters include the type and strength of the magnetic field, the timing and duration of radiofrequency pulses, and the way that the signals from the body are detected and processed. There are many different MRI sequences that can be used, each with its own advantages and disadvantages for different types of imaging.

A series in MRI refers to a set of MRI images that are acquired using the same sequence but with different settings or parameters. For example, a series of images may be acquired with different echo times (TE) or repetition times (TR) to highlight different tissues or pathologies. These images can be displayed separately or combined into a single image that shows different contrasts.

MRI sequences and series are important tools for diagnosing and monitoring a wide range of medical conditions, as they allow doctors to visualize the body's internal structures in detail and to detect abnormalities that may not be visible with other imaging techniques. By selecting the appropriate sequence and series for a particular patient and condition, doctors can obtain the most informative and accurate images possible.

 Teleradiology, Patients and MRI Terms: TeleradiologyHub Explains

It's great to hear that TeleradiologyHub provides clear and informative explanations for MRI second opinion seekers regarding sequences and series in MRI. Providing clear information about medical imaging techniques is important for patients to understand their diagnosis and treatment options, and it can also help to improve communication between healthcare providers and patients.

In addition to explaining sequences and series, it's also important for second opinion providers to communicate any relevant findings or abnormalities that may be present on the MRI scan. This information can help patients make informed decisions about their treatment options and can also assist their healthcare providers in developing a tailored treatment plan.

Overall, clear communication and education about medical imaging techniques and findings can help patients to feel more confident and informed about their health, and can ultimately lead to better health outcomes.
