Are MRI And Ultrasound Scans an Alternative To CT Scans?

Different diagnostic options have quite distinct functions and assist physicians in obtaining a clearer image of various body areas in different ways. For instance, portions of the body possessing calcium (such as bones) or air (such as the lungs) might not be readily seen on an ultrasound or MRI scan; thus, a CT scan is necessary. Additionally, in emergencies, like whenever a patient has sustained a head injury, a CT scan is recommended over an MRI scan because it is speedier.

Besides, in instances of trauma, patients cannot be sedated and might move throughout the scan. MRIs are particularly sensitive to motion, culminating in motion distortions that could impact the diagnosis. CT scans, on the other end, are less vulnerable to motion. Your physician at St. Michael’s Elite Hospital will recommend the optimal scan based on the particulars of your situation. However, you should never be reluctant to approach your practitioner for alternatives.

Why Is A Contrast Dye Necessary, and What Should You Know?

A contrast agent highlights inside body features, helping your physician make a highly precise diagnosis. The contrast dye works similar to shining a light on troubled parts of the body, but on the inside. Prior to receiving a scan with contrast dye, you will be required to fast for three hours. The dye will be provided 45 minutes prior to the scan as either a drink to be consumed or an intravenous injection.

Numerous patients fear the contrasting agent’s negative effects. Nevertheless, problems are uncommon and generally treatable. Some individuals may feel loose stools for a day or so following the scan, but this is temporary. However, ensure that you inform your physician if you are allergic or sensitive to specific medications, are using diabetes medication, or have renal difficulties, as it might cause complications with the contrast dye.

Why Is Serum Creatinine Reporting Necessary?

Most imaging clinics, including St. Michael’s Elite Hospital, require a serum creatinine analysis if you are receiving a CT scan. This report monitors the quantity of creatinine within your blood to determine how well your kidneys eliminate contaminants. This report is significant since contrasting material might not be suitable for individuals with compromised renal function, as the kidneys might not efficiently filter the substance from the body.

Can A CT Scan Be Performed If You Have A Pacemaker?

Yes! Patients using pacemakers and other implants can securely undertake a CT scan as opposed to an MRI since the latter contains a strong magnet that could be harmful to those with implantable devices. Nevertheless, metal items should not be worn during your CTS scan, such as jewelry. Although these items might not be deadly to your procedure, they will hinder the scan’s quality and effectiveness.

Should You Be Concerned About The CT Scan’s Radiation Exposure?

As a CT scan utilizes potent X-rays, numerous persons are concerned about radiation exposure. Conversely, the radiation dose from a single CT scan is low. Besides, modern scanners limit radiation levels, whereas qualified physicians modify the amount for every patient based on their age and individual situation. What’s more, CT scans are only suggested when the advantages significantly outweigh the risks, such as when identifying and correcting life-threatening conditions.

Now that you understand the basics about a CT scan, should you have one? For a definitive answer, it is best to talk to an expert.
