Revisiting India’s Ultrasound Laws
Subject: Science & Technology | Governance | Health
Context
The Pre-Conception and Pre-Natal Diagnostic Techniques (PCPNDT) Act, 1994 has recently come under renewed debate, with experts advocating reforms that preserve its objective of preventing sex-selective practices while improving access to essential diagnostic healthcare, particularly in rural India.
The discussion gained attention after the case of a rural woman with a breast lump, whose delayed diagnosis—caused by poor access to ultrasound services—resulted in advanced-stage breast cancer and death.
Why is Reform Being Discussed?
Recent advances in portable ultrasound technology now enable diagnostic services such as:
- Breast imaging,
- Ultrasound-guided biopsies,
- Point-of-care diagnostic screening.
However, under the PCPNDT Act, moving an ultrasound machine outside a registered facility is a punishable offence, limiting community-based diagnostic services in rural and underserved areas.
About the PCPNDT Act, 1994
Objective
The Pre-Conception and Pre-Natal Diagnostic Techniques (PCPNDT) Act, 1994 was enacted to prevent female foeticide by prohibiting the misuse of prenatal diagnostic techniques for sex determination.
Need for the Act
- Declining Child Sex Ratio (CSR)
- Widespread misuse of ultrasonography for prenatal sex determination
- Persistent gender discrimination against girls
Key Provisions of the PCPNDT Act
- Mandatory registration of:
- Genetic counselling centres,
- Genetic laboratories,
- Genetic clinics,
- Ultrasound and imaging centres.
- Prohibits
- Prenatal sex determination.
- Disclosure of the sex of the foetus.
- Prescribes stringent penalties for violations, including imprisonment, fines, and suspension or cancellation of medical licences.
- Strict regulation of ultrasound machines
- Ultrasound machines can be purchased only after registration of the healthcare facility.
- Manufacturers and dealers must verify buyers before selling equipment.
- Every machine must remain at its registered location.
- Detailed records of every ultrasound examination must be maintained.
Achievements of the Act
The Act has contributed to a gradual improvement in India’s Sex Ratio at Birth (SRB) by reducing the misuse of prenatal diagnostic technology, although the extent of its impact remains debated.
Unintended Consequences
Research suggests that restrictions on prenatal sex selection have also produced several unintended outcomes.
Higher Fertility
- Families with a first-born girl often have more children in pursuit of a male child.
Higher Child Mortality
- Studies indicate nearly 25% higher mortality among first-born girls compared to boys in such households.
Resource Dilution
Larger family sizes have reduced investments in:
- Healthcare,
- Nutrition,
- Education,
with girls being disproportionately affected.
Greater Impact on Poor Households
The adverse effects are more severe among poor and rural families, who have limited access to quality healthcare and cannot circumvent legal restrictions.
Continuing Challenges
Despite strict legal provisions, illegal prenatal sex determination networks continue to operate.
Recent Karnataka Crackdown (2025)
Authorities uncovered organised rackets involving:
- Portable ultrasound devices,
- Secret scanning locations,
- Illegal sex-selective abortions.
These cases indicate that illegal activities have shifted outside formal healthcare institutions rather than being completely eliminated.
Reports also suggest that son preference persists among certain Indian diaspora communities, indicating that the problem is rooted in social attitudes rather than geography alone.
Challenges Faced by Healthcare Providers
Experts argue that the stringent implementation of the PCPNDT Act has created a “chilling effect” on legitimate healthcare providers.
Doctors often avoid using portable ultrasound technology due to fear of:
- Legal action,
- Administrative penalties,
- Procedural lapses.
The law has also failed to keep pace with rapid technological advancements.
Emerging Technologies
1. Portable & Handheld Ultrasound
Modern handheld ultrasound devices connected to:
- Smartphones,
- Tablets,
can significantly improve healthcare delivery in rural areas.
Importantly, many high-frequency linear ultrasound probes used for:
- Breast cancer detection,
- Soft tissue imaging,
- Musculoskeletal disorders,
are technically incapable of determining foetal sex.
However, they remain subject to the same regulatory restrictions under the PCPNDT Act.
2. Artificial Intelligence (AI)-Enabled Ultrasound
AI has significantly expanded the capabilities of portable ultrasound systems.
AI-assisted devices can:
- Guide image acquisition,
- Assist interpretation,
- Generate automated reports using pattern recognition.
These systems can also be designed to:
- Prevent storage of foetal images,
- Block display of foetal anatomy,
- Eliminate the possibility of prenatal sex determination.
Evidence
Pilot studies show that frontline healthcare workers with minimal training, assisted by AI-enabled portable ultrasound, can accurately identify suspicious breast lesions requiring specialist referral.
This technology has significant potential for:
- Early breast cancer detection,
- Timely referral,
- Improved treatment outcomes,particularly in areas where radiologists are scarce.
Why Does India Need Such Reforms?
- Nearly 70% of India’s population resides in rural areas, where access to advanced diagnostic imaging remains limited.
- Mammography-based screening programmes used in developed countries are resource-intensive and difficult to implement widely in India.
- Portable AI-assisted ultrasound offers a cost-effective and accessible alternative for diagnosing symptomatic patients.
Suggested Reforms
Experts recommend amending the PCPNDT Act to distinguish between different clinical uses of ultrasound.
Proposed Measures
- Permit community-based ultrasound services using high-frequency linear probes that cannot determine foetal sex.
- Introduce provisions for AI-enabled safeguarded ultrasound systems that technically prevent the determination or disclosure of foetal sex.
- Adopt a risk-based regulatory framework instead of applying uniform restrictions to all ultrasound devices.
- Strengthen monitoring and enforcement against illegal sex determination while facilitating legitimate diagnostic services.
Way Forward
A balanced reform of the PCPNDT Act should preserve its core objective of preventing female foeticide while enabling wider access to life-saving diagnostic technologies. Leveraging portable ultrasound, AI-assisted imaging, and technology-based safeguards can improve early disease detection, especially for breast cancer in rural India, without compromising the fight against sex-selective practices.
