DTPA Scan
Assessing Kidney Function With DTPA Scan
A DTPA
(Diethylenetriaminepentaacetic acid) is a medical imaging technique generally
used for evaluating kidney functioning and assessing renal blood flow. It is
used to understand and identify any abnormalities that may arise in the kidney
related to blood flow such as renal artery stenosis. These scans are crucial in
diagnosing and monitoring various kidney conditions such as acute kidney
injury, chronic kidney disease, or renal obstruction. DTPA scans have emerged
as crucial diagnostic tools in nephrology and vascular medicine helping
healthcare providers make informed decisions regarding patient care and
treatment plans.
Overview of the Key Aspects of DTPA Scan
Importance of DTPA Scan:
DTPA scans are a
part of nuclear medicine imaging and are used to assess kidney function and
detect any renal blood flow issues. This scan plays an important role in
helping healthcare providers understand how each kidney is contributing to the
overall kidney functioning. DTPA scans can also be included in ongoing medical
care to monitor the treatment response in patients with known kidney condition
or those at-risk of kidney diseases. In addition, these scans play a vital role
in the research and clinical studies focused on kidney diseases and treatment
and help in development of new therapies and treatment measures.
Procedure:
●
Before the scan, patients may
be advised by their healthcare providers to fast a few hours before the
procedure and to drink plenty of fluids.
●
Patients will be then informed
about the test, it’s purpose and what to expect.
●
A small IV line is then
inserted into a vein in the arm of the patient which is then used to administer
the radioactive tracer in the bloodstream.
●
Once the IV line is stabilised,
the tracer is injected and patients may experience a metallic taste in the
mouth for a short period.
●
After the injection, patients
may need to wait for a specific period to allow the tracer to be circulated
properly through the bloodstream and then absorbed by the kidneys.
●
When the waiting period is
completed, the patients will be asked to lie down on the examination table.
●
A gamma camera or specialized
imaging device is used to capture images of the kidneys.
●
The photos will be taken from
different angles to provide detailed information about kidney function and
blood flow.
●
Once the imaging is done, IV
line is removed and patients can resume their normal activities.
●
The images obtained will then
be interpreted by the radiologist or healthcare provider and discussed further
to determine the appropriate treatment options required.
Benefits:
●
Relatively painless with
minimal side effects
●
Highly effective in assessing
kidney functions such as filtration of blood, removal of waste materials, and
maintenance of electrolyte balance
●
Effectively detect problems
related to renal blood flow and prompt timely interventions
●
Enables individual assessment
of each kidney’s function and is very helpful in determining kidney functioning
when one kidney is compromised due to disease, injury, or congenital
abnormalities
●
Helps in monitoring and
managing kidney diseases and treatment response
●
Crucial in pediatric medicine
as it helps in early diagnosis of kidney diseases and implementing appropriate
healthcare strategies in children
Patients must inform their healthcare provider about their medical history, current and ongoing medications, allergies, and underlying medical conditions to ensure no complications arise during the procedure. Special precautions must be taken for a pregnant/breastfeeding patient as radioactive tracers can be harmful for the fetus/baby. Patients must inform their healthcare providers if they have any allergies to contrast materials to avoid any complications. It is important for patients to stay still during the imaging to ensure clear and accurate images. While the radiation dosage is controlled, it is imperative for the patients to inform their healthcare provider if they’ve undergone any radiation treatment recently to avoid over-exposure to radioactive materials.
