📋 PNDT Applicability in X-ray, CT & MRI

🔹 1. X-ray

• X-rays use ionizing radiation, harmful for fetus.

• X-ray machines are covered under PNDT Act only if used for pre-natal diagnosis.

• Rule: A diagnostic center with an X-ray unit must declare in writing that it will not use X-ray for pregnant women for fetal sex determination.

• Registration under PNDT is required only if X-ray is used for pre-natal purposes.

• Usually, routine diagnostic X-ray centers do not register under PNDT, but must display a board:
  “Sex determination is prohibited and punishable under PNDT Act”.

🔹 2. CT Scan

• CT uses high dose ionizing radiation.

• Same rule as X-ray – CT scan of abdomen/pelvis in pregnancy can indirectly reveal fetus.

• If CT scan center provides pre-natal diagnostic services → PNDT registration mandatory.

• If the CT scan is general diagnostic only, then usually no PNDT registration, but declaration & display board are compulsory.

---

🔹 3. MRI

• MRI uses magnetic field & radio waves (no ionizing radiation).

• MRI of pelvis/abdomen in pregnancy can also visualize fetus & sex.

• Hence, MRI centers fall under PNDT Act if used for pre-natal diagnosis.

• Even if not doing obstetric MRI, most authorities insist that MRI centers take PNDT registration or at least declare non-use for sex determination.

✅ Summary Table – PNDT Applicability

Modality	PNDT Registration Required?	Notes
X-ray	✔️ If used for pre-natal diagnosis	Otherwise, must display “No sex determination” board.
CT Scan	✔️ If abdomen/pelvis scans for pregnant women are done	Otherwise, declaration only.
MRI	✔️ If fetal/pregnancy MRI is done	Even diagnostic MRI centers are often asked to register or at least declare.

⚠️ Important

• Every radiology center (X-ray, CT, MRI, USG) must display a board:
  “Disclosure of sex of the fetus is prohibited under the PC-PNDT Act”.

• Ultrasound centers are strictly under PNDT, but X-ray/CT/MRI also come under PNDT if fetal imaging is done.

• Many districts in India ask even MRI & CT centers to apply for PNDT registration as a precaution.
