Dr Kshama Wechalekar is the lead consultant in nuclear medicine at Royal Brompton Hospital.

Kshama qualified from Nagpur University, India, in 1996. She trained in general nuclear medicine in India at the Radiation Medicine Centre and at Jaslok Hospital, Mumbai, and received her qualification in 1999.

After moving to the UK, she completed further training at Royal Brompton and Royal Marsden hospitals for four years. She gained specialist knowledge in nuclear cardiology and oncology including PET-CT. She also has a specialist qualification in nuclear cardiology from both the American and European nuclear cardiology boards.

In 2008, she became a consultant in nuclear medicine at Royal Brompton Hospital. Since 2011, she has led a team providing specialist radionuclide imaging services.

She is responsible for PET-CT facility at 77 Wimpole Street, Royal Brompton & Harefield Hospitals Specialist Care’s outpatient service in central London.

Clinical expertise

Dr Wachalekar’s areas of expertise include:

  • nuclear imaging of the heart and lungs
  • using hybrid imaging techniques, such as SPECT-CT and PET-CT, to improve understanding of pathophysiological processes affecting heart and lungs
  • imaging of inflammation and infection using PET-CT
  • imaging for cardiac and systemic sarcoidosis using PET-CT

Cardiac sarcoidosis is life-threatening, but an under-diagnosed condition. Dr Wechalekar worked with experts at the Trust, designing a diagnostic algorithm for this condition. It helps clinicians diagnose, assess treatment responses, and track therapy with PET-CT scans.

Dr Wechalekar has extensive experience in myocardial perfusion imaging. She led development on a new method of gauging lung function for patients undergoing lung surgery. She believes in the strength of multimodal imaging in better understanding of disease processes.


Dr Kshama Wechalekar has developed new method of 3D lung quantification (in collaboration with a software company) to produce lobar quantification of lungs, using dedicated CT and SPECT-CT methods.

She worked on brain perfusion scans in HIV positive asymptomatic patients towards the award of DNB.


Dr Kshama Wechalekar has written papers for many peer-reviewed journals and review articles. She has authored book chapters and presented work at national and international meetings. She has also been a reviewer for nuclear medicine journals.


Dr Kshama Wechalekar teaches nuclear cardiology at Imperial College London, and MSc students at King’s College London.
