INTERVENTIONAL RADIOLOGY
Radiology interventional methods, interventional neuroradiology, interventional radiology jobs
A radiologist is a doctor who does the diagnosis of diseases with the help
of a CT scan or x ray. Some radiologists specialize in Interventional Radiology.
This Interventional Radiology helps in diagnosis and treatment of the patient.
The Interventional Radiologist uses special instruments or tools such as
catheters, or wires. They insert these inside the body to reach the affected
site using CT Scanners, MRI Scanners, ultra sound scanners. The wire has
a camera attached to it which is viewed either directly or sometimes seen
in the monitor. Suppose they find a foreign body inside the body they will
remove it with the help of another special instrument. Hence, surgery can
be done without cutting the body, but can through only one small hole. This
reduces hospitalization of the patient some times they are done as day cases.
The Interventional Radiologist is a doctor who does Radiology study for
four years, in the Medical School .After completion he becomes eligible
to take the Board Examination given by the American Board of Radiology .
Once the board exam is over he takes up training in Interventional Radiology
and then finally becomes an Interventional radiologist. They get jobs easily
in community hospital .They work with other physicians and solve the problems
of the patients without surgery.
After becoming a full fledged Interventional Radiologist they will be ready
to do angiography, embolization, gastrostomy tubes, intravascular ultrasound,
stent placement, foreign body extraction, needle biopsy, blood clot filters,
injection of clot lysing agents,
Catheters insertion and cancer treatment.
Angiography is done to a heart patient with angina. He might have some blocks
in the arteries which are detected with the help of angiography .They inject
a dye and with the help of the wire inserted they detect the arteries that
are blocked in the monitor attached to it. Sometimes if there is critical
block they will be taken for Bypass surgery otherwise a stent is inserted
and inflated which opens up the vessel. This process is called angioplasty,
When insertion of a substance is done through a catheter into a blood vessel
to stop hemorrhaging or excessive bleeding, it is Embolisation. Gastrostomy
tubes are inserted into the stomach if the patient is unable to take food
by mouth.
To find the problems inside the blood vessel intravascular ultra sound is
used. It gives a clear vision of the interior of the vessel.
Any foreign body inside the body can be detected and taken out using a catheter.
In the case of cancer patients a needle is inserted in the affected area
and a tissue biopsy it taken without surgery. The invention of Interventional
Radiology has given the Medical field a change in the way of treatment;
soon the use of knife may be stopped.
