Importance of CT- Angiography

• Doctors use angiography to detect and treat
  problems with the cardiovascular system's blood
  vessels. Angiography procedures capture images of
  the body's major arteries. Contrast material is
  used in some diagnostic procedures.
• To do angiograms, doctors use- 
• Catheterized x-rays
• CT scans, or computed tomography
• Imaging with a magnet and radio waves

To create high-resolution images of blood
arteries and surrounding tissues, CT angiography
uses computed tomography (CT). Contrast material
is administered through a catheter into an arm
vein during the exam. While the contrast material
is pumped through the patient's veins and
arteries, a CT scan will be performed to obtain
high-resolution images.
What is the process like?

Traditional X-ray imaging and CT scanning share
many commonalities. In standard X-ray imaging, a
single X-ray source fires a beam of rays across
the patient's body. A detection plate captures
the X-rays emitted from the body. The image will
appear in varying colors of grey depending on how
much X-ray light is blocked by various human
organs. On an X-ray, bones appear white, while
air looks dark. In CT scans, several X-ray beam
sources and arrays of X-ray detectors spin
rapidly around the patient's body. The X-ray beam
sources send multiple narrow beams with high
energies through the body. The detectors detect
the X-rays released from the body and will be
rolled through the CT scanner to expose various
body parts to the scanner's X-ray beams. After
collecting data from the scanner, a powerful
computer will use it to create images of the
human body.  The computer generates two- and
three-dimensional images of the body from a vast
amount of CT scan data. Radiologists will use
high-tech computer software and display to
examine these images for signs of disease. To
see the blood arteries clearly, contrast material
is used during procedures to make them seem stark
white.

• How should one be prepared for CT- Angiography
• Dress loosely and comfortably for the exam.
• The CT pictures may be distorted if the patient
  wears metal objects such as jewelry, eyeglasses,
  dentures, or hairpins. 
• Underwired bras made of metal must be removed.
  You should stop getting pierced.
• Your doctor will suggest you fast for a certain
  amount of time before your exam if contrast
  material is used. 
• Inform your doctor about undergoing medications
  or any allergies. Your doctor may give drugs
  (often steroids) to lessen the likelihood of an
  adverse reaction if you have a history of
  sensitivity to contrast material. 
• If a woman has any reason to suspect she is
  pregnant, she should tell both her doctor and the
  CT tech.

The Importance of CT Angiography
Detailed images of the inside of your head, neck,
body, legs, and arms help doctors diagnose. It is
non-invasive, precise, and rapid, and it may be
used in real-time to monitor the condition of
blood arteries during surgical procedures. While
CT scans expose patients to radiation, the amount
absorbed by the body is negligible.

• Avoid surgery using angiograms. Accuracy in
  surgery is improved if it is still required.

• When compared to traditional angiography, CT
  angiography has the advantages of being quick,
  painless, and less prone to problems.
• Compared to more traditional forms of
  angiography, such as catheter angiography or
  magnetic resonance imaging (MRI), CT angiography
  can offer more accurate anatomical data.
• Sedation or general anaesthesia is unnecessary
  for CT angiography.
• Coronary artery blockages can be detected via CT
  angiography of the heart.
• CT angiography may be less expensive than
  catheter angiography.
• After a CT exam, the patient is exposed to no
  residual radiation.
• Protecting Yourself from Radiation A Word
• During X-ray examinations, doctors take extra
  precautions to limit radiation exposure while
  capturing clear images for diagnosis. The
  procedures followed by radiologists are subject
  to constant scrutiny and revision by national and
  international radiological protection
  organizations.

Controlled X-ray beams and dose control
procedures are used in modern X-ray systems to
reduce the amount of unwanted stray (scatter)
radiation. This reduces radiation exposure to
parts of your body that aren't being scanned. CT
angiography will be performed with as little
radiation as possible using scan parameters
customized to your body. Scan areas will be
restricted to the target organ to reduce exposure
to unneeded radiation.
