Renal DTPA Scan in Dhakuria

The renal DTPA & EC scan is a diagnostic imaging procedure used to assess kidney function and detect abnormalities. It involves injecting a radioactive tracer, technetium-99m diethylenetriamine penta-acetic acid (DTPA), into the bloodstream, which is filtered by the kidneys. Specialised cameras capture images of the kidneys, including the early clearance phase (EC), providing insight into renal function and blood flow. 

This non-invasive procedure helps diagnose conditions such as kidney stones, infections, or tumours and assesses blood flow to the kidneys. The scan is relatively safe, with minimal risks associated with the tracer. Results guide treatment decisions and monitor disease progression, contributing to improved patient outcomes and quality of care in managing kidney-related conditions.

FAQ's

A renal DTPA scan is a painless and non-invasive imaging technique that helps diagnose various anomalies within the kidney. It helps doctors diagnose a kidney disease in its early stages and helps decide the right treatment. Some of the indications for the scan are:

  • High blood pressure in renal arteries

  • Renal artery stenosis

  • Hydronephrosis

  • Polycystic kidney disease

  • Kidney abscess

  • Assessment of kidney function following a transplant

When the patient is coming for the renal DTPA scan (diethylenetriamine pentaacetic acid), they are advised to bring the doctor’s prescription or previous scan reports to generate appropriate scan reports. The patient is asked to change into a gown and remove all metal objects that could interfere with the scan.

Drink one litre of water within an hour before the exam, and use the restroom as needed. If you take any medicine for high blood pressure, let the practice know. If you are pregnant or breastfeeding, inform your doctor before the scan.
 

A radioactive tracer called a radioisotope is injected into the vein during the DTPA & EC renal scans. The radioisotope releases gamma rays in the kidney area, which are detected by the gamma camera with a computer from outside the body, creating 2D and 3D images of the organ. These images show the structure and functioning of the kidneys based on their reaction to radioactive material. Assessment of the kidney’s blood supply, excretion of urine, and drainage pattern helps identify any blockage or obstruction in the kidneys.

Depending on the patient’s medical history, the scan takes thirty to forty minutes. Following the scan, safety guidelines are given, which include drinking plenty of fluids after the scan and avoiding contact with infants and pregnant women for 24 hours.

In general, a renal DTPA and EC scan are painless. Although there may be some minor discomfort during the radioactive tracer injection, it is usually brief and bearable. As the tracer circulates, patients may feel hot or have a metallic taste for a brief time, but overall, the scan is well tolerated. 
 

Kidney problems can be diagnosed with the help of renal DTPA & EC scans, which provide vital diagnostic data for customised treatment regimens. When treating illnesses like kidney stones, infections, or tumours, medical professionals can start the right course of treatment sooner by using precise images of kidney function and blood flow. 

The scan also makes it possible to track changes in kidney function over time and evaluate the efficacy of treatment. In general, the scan informs treatment choices, improving patient outcomes and patient care while addressing renal problems.

An EC and DTPA scan of the kidney usually takes 30 minutes to 1 hour. Preparation, the radioactive tracer injection, and imaging scans to evaluate blood flow and kidney function are all part of the operation. For a seamless experience, patients should adhere to the precise directions given by healthcare professionals.

A diuretic like Lasix (furosemide) may be given before a renal DTPA and EC scan to increase tracer excretion and enhance imaging clarity. Pre-medication needs, however, differ according to facility policies and personal health characteristics. It is essential to follow any special instructions given by medical professionals to maximise the scan's efficacy and safety. 

This prophylactic action aids in a thorough assessment of blood flow and renal function. Following pre-scan protocols ensures correct renal status assessment and management during the scan.
 

It is helpful to flush the radiotracer from the body for 24 hours following an EC renal scan by consuming plenty of water. A radiologist or nuclear medicine professional usually interprets the scan and creates the report. 

Patients are recommended to seek emergency medical assistance if they develop any adverse effects, including pain, redness, swelling, or infection-related symptoms. It is important to treat these symptoms immediately to maintain patient safety and avoid any scan-related health complications.
