A CT scan, also known as computed tomography scan, is an X-ray procedure that uses special x-ray equipment to create detailed pictures, or scans, of areas inside the body. It is used to evaluate bones and joints, as well as soft tissue structures such as the lungs, heart and blood vessels. CT scans are often ordered for patients who have suffered a trauma, such as a car accident or a fall, or who have symptoms that require more information than can be provided by a traditional X-ray.
Lesson 1: You Shouldn't Eat or
Drink Before a CT Scan
If you're scheduled for a CT
scan in CT Scan CenterIn Dwarka,
you'll need to fast for a period of time before the test. This is because food
and drink can interfere with the CT scan images. You'll typically be asked to
fast for four to six hours before a CT scan. In some cases, you may be asked to
fast for up to 12 hoursIt's important that you follow your doctor's
instructions regarding fasting before a CT scan. If you don't fast as directed,
the CT scan images may be blurry and unusable.
Lesson 2: You May Be Given
Contrast for Your CT Scan
Contrast refers to a substance
that is used to enhance the images produced by a CT scan. Contrast material is
generally safe, but there are a few potential side effects, such as hives,
headache, nausea and vomiting. In very rare cases, contrast material can cause
an allergic reaction that requires emergency treatment.If you're scheduled for
a CT scan with contrast, your doctor will likely give you specific instructions
regarding how to prepare. In most cases, you'll be asked to drink plenty of
fluids and empty your bladder completely before the CT scan.
Lesson 3: You May Need to Hold
Your Breath During a CT Scan
Most CT scans are performed
while the patient is lying down on a table that slides into the center of the
CT scanner. The scanner itself is large and round, like a doughnut. As the
table slides into the center of the machine, the scanning process will begin.
During some types of CT scans, such as those of the chest or abdomen, you may
be asked to hold your breath for a short period of time. This is because
breathing can cause movement that can blur the CT scan images.
Lesson 4: CT Scans are Usually
Painless
CT scans are generally painless
procedures. The only thing you'll feel during the CT scan is the slight
pressure of the table against your body and the warmth of the contrast material
as it's injected into your IV line.
Lesson 5: CT Scans are Usually
Outpatient Procedures
Most CT scans are performed on
an outpatient basis, which means you won't need to stay overnight in the
hospital. In some cases, however, such as when CT scans are used to diagnose
cancer or other serious conditions, you may need to stay in the hospital for a
brief period of time. After the CT scan is complete, you'll be able to go home
and resume your normal activities. In most cases, there are no restrictions on
activity after a CT scan. However, if you received contrast material through an
IV line, you'll need to drink plenty of fluids to help flush the contrast
material out of your body.
