DTPA/EC Scan

Overview

A DTPA (diethylene triamine pentaacetic acid) or EC (ethylene dicysteine) scan is a nuclear medicine test used to assess kidney function, blood flow, and possible obstructions in the urinary system.

Your doctor may recommend a DTPA/EC renogram scan for evaluating various conditions, such as:

  • Evaluating the kidney function
  • Checking for kidney obstructions or blockages in the urinary tract
  • Monitoring the status of kidney transplants
  • Diagnosing conditions affecting blood flow to the kidneys

The DTPA/EC scan involves the following steps:

  • A small amount of radioactive tracer is injected into a vein.
  • Sometimes, a small dose of a diuretic (such as furosemide) may be administered as part of the protocol to assess the state of kidney obstruction.
  • You will be asked to lie down, and a special camera (gamma camera) will capture images, tracking the tracer through your kidneys.
  • The initial scan, called the dynamic phase, usually takes 30 minutes. Thereafter, additional shorter scans (called static scans) are acquired at specific time intervals as per the doctor’s instructions.
  • You will be asked to lie still during the imaging to ensure clear results.

The main scan takes about 30 minutes, but with additional images, the entire process may last up to 1–2 hours, depending on your doctor’s instructions.

Most patients need little preparation, but it is important to follow your doctor’s advice:

  • Fasting: Not usually required prior to the scan.
  • Hydration: Drink plenty of water before your scan (unless otherwise directed or advised of fluid restriction by your doctor). This helps your kidneys process the tracer more effectively.
  • Medications: Inform your doctor if you have undergone any recent barium or contrast-enhanced CT scan within 48 hours prior to the test. Additionally, inform your doctor about any medications you take, as some may affect the results.

  • The amount of radioactive tracer used is minimal and leaves your body within 24 hours.
  • Allergic reactions are extremely rare, but you should discuss any concerns or allergies with your healthcare provider before the scan.
  • The procedure is safe for most patients; however, always inform your doctor if you are pregnant or breastfeeding.

  • You can resume normal activities immediately after the test. There are no dietary constraints.
  • Drink extra fluids over the next 24–48 hours to help flush out the tracer from your body faster.
