MRI Scanning in Dhakuria

MRI is an important diagnostic tool that aids healthcare providers in planning treatment and all the necessary interventions. MRI is a non-invasive imaging technology where 3-dimensional images of the required elements are produced using magnetic resonance and radiowave technology. This diagnostic aid produces detailed images, which help in the diagnosis and early detection of diseases and can also help in monitoring the treatment course and how the body is responding to the particular therapies given. 

This MRI machine is a huge set-up with a large dome-shaped tube with a slider in between the tubes, allowing the patient to slide into it. This differs from conventional CT scans and X-rays in producing detailed images and minimising risks during the procedure.

FAQ's

An MRI is used to diagnose and monitor a variety of conditions. It’s particularly useful for examining soft tissues, such as the brain, spinal cord, muscles, and organs. Common reasons for an MRI include:

  • Detecting Tumours: To identify and assess the size and location of tumours.

  • Assessing Injuries: To evaluate injuries to soft tissues, such as ligaments and muscles.

  • Diagnosing Neurological Conditions: To investigate conditions like multiple sclerosis or stroke.

  • Monitoring Treatment: To check the effectiveness of ongoing treatment for certain conditions.

The intense magnets used in MRIs generate robust magnetic fields that cause protons in the body to align with them. When a radiofrequency current is directed into the patient, the protons become stimulated and deviate from their balanced state, resisting the pull of the magnetic field.

Gadolinium is a type of contrast agent used in certain MRI scans. It's a rare earth metal that modifies water molecules' magnetic characteristics. The diagnostic images become sharper and more exact as a result. The following are made more visible by the contrast material:

  • Tumours
  • Inflammation
  • Infection
  • Blood flow to specific organs

An IV catheter will be inserted in a vein in your hand or arm if a contrast agent is required for your MRI. Through this IV, contrast material is provided. Although mild to severe side effects may occur, the use of contrast materials in MRI scans is generally considered safe, and serious reactions are rare.

Depending on the area being scanned, you may lie on a flat bed that moves into the scanner head or feet first during an MRI scan. To avoid the magnetic field, a radiographer uses a remote control to run the scanner from a separate room. Through an intercom, you can stay in communication while the radiographer keeps an eye on you through a viewing glass and television. Earplugs or headphones are given since the scanner produces loud tapping noises when the electric current in its coils changes on and off. For the duration of the scan, which takes 15 to 90 minutes, you must remain still. In addition, the radiographer might urge you to hold your breath or do other things.

An MRI modality known as a functional MRI (fMRI) is used to map brain activity. Using an fMRI, doctors can observe the areas of your brain that become active during certain tasks to assess cerebral blood flow. This can also aid in identifying brain disorders like stroke, Alzheimer's, or injury. In cases of brain surgery for conditions such as tumours or treatment planning.

Patients who suffer from claustrophobic anxiety may feel scared and confined during magnetic resonance imaging (MRI) exams. These patients may require special attention, sedation, and additional sequences (post-sedation) to complete their exams. To address patient concerns, the doctor and radiologist will be present to guide them through the entire procedure. Some medical facilities offer open MRI scanners for specific body areas to accommodate individuals with claustrophobia. To reduce anxiety before an exam, patients can take medication.

MRI's drawbacks include:

  • MRI scans cost more than CT scans.

  • Patients may feel uncomfortable because MRI scans typically require more time to obtain compared to CT scans.

  • The noise level in MR image capture is higher when compared to CT.

  • Compared to CT scanners, MRI scanners are typically more confined, which can cause claustrophobia.

  • There are specific artefacts associated with MR pictures that need to be identified and countered.

  • Patients who have foreign entities or certain metal implants should not undergo MRI scanning. To prevent major injuries to patients and personnel, safety precautions must be closely monitored. This calls for specialised equipment that is compatible with MRIs and strict adherence to safety procedures.

Although having an MRI is a highly safe operation, there are a few things you should know before going ahead. It can be challenging for certain people to lie still in a limited area. Although most are longer, they can last as little as ten minutes. An MRI scan may take up to two hours to complete. Make sure you let the doctor know if you have a phobia of cramped or small areas. Medication can be an option for you to help you relax during the scan. To keep them motionless, newborns and young children could require a general anaesthetic.

Before the examination, remove some common types of jewellery, including watches, necklaces, earrings, and rings. Other items that should be removed before the test are sharpeners, pens, and spectacles. Additionally, any cards containing magnetic information, like credit cards, should also be taken out. Hairpins, pins, and other metal objects that resemble them can also distort MRI images. Lastly, clothing with metal hooks, buttons, zippers, and other hardware should be avoided.
