Dr Deepak Krishnamurthy, a cardiologist with more than 25 years of clinical experience, has warned that the increasing push for frequent MRI scans can harm patients instead of helping them. His remarks come in response to recent online discussions triggered by Elon Musk’s suggestion that people should undergo regular full body MRI scans analyzed by artificial intelligence to detect diseases early.
While the idea gained attention due to Musk’s influence and emphasis on technology driven healthcare, Dr Krishnamurthy cautioned that medicine cannot rely on blanket screening approaches without clinical reasoning. He stressed that MRI scans are powerful diagnostic tools but are dangerous when used without clear medical indication.
The debate intensified after Elon Musk publicly suggested that annual MRI scans, combined with AI-based analysis, could potentially prevent deaths by identifying hidden diseases early. Supporters of the idea argue that advanced imaging and artificial intelligence could transform preventive healthcare.
The idea of routine yearly MRI scans gained attention after public figures promoted the use of artificial intelligence to analyze scans and identify hidden diseases. Supporters argue that early detection can save lives. However, Dr. Krishnamurthy explained that this logic oversimplifies how healthcare works.
MRI machines are extremely sensitive and often detect small structural changes that may never cause symptoms or impact a person’s health. These findings are commonly labelled as abnormalities, even when they are harmless.
Once such results appear in a report, patients often feel alarmed and pressured to take further action, even when doctors advise that no treatment is needed.
Dr. Krishnamurthy highlighted overdiagnosis as one of the biggest dangers of excessive MRI use. Overdiagnosis occurs when scans detect conditions that would never have caused illness or death.
These findings often lead to additional scans, specialist visits, biopsies, or even surgeries. Each step introduces new risks, physical discomfort, and emotional stress.
He pointed out that some MRI scans require contrast agents, which may cause side effects in certain patients. Invasive procedures performed after incidental findings can lead to complications that outweigh any potential benefit.
The psychological toll of unnecessary MRI scans is significant but frequently overlooked. Dr. Krishnamurthy noted that once patients hear the word abnormal, reassurance rarely erases fear completely.
Many patients experience anxiety, constant worry, and repeated health related stress after incidental findings. This can affect sleep, daily functioning, and overall quality of life.
Instead of feeling reassured, patients may become trapped in a cycle of testing that offers little clarity or comfort.
