Dr Thomas Semple

Dr Thomas Semple is a cardiothoracic specialist with expertise in the imaging of heart and lung conditions in neonates, infants, children, and adults.

In 2009, Dr Semple graduated from Kings College, London, and in 2016 completed his postgraduate radiology training at the University College London Hospitals’ (UCLH) training scheme. After completing his cardiac CT and paediatric radiology fellowship at Royal Brompton, Great Ormand Hospital and University College Hospital, Dr Semple undertook a two-year structural and functional lung magnetic resonance imaging (MR) fellowship at Royal Brompton, where he currently works.

Dr Semple is the clinical lead for congenital cardiac CT at Royal Brompton, and provides radiology input for multi-disciplinary team meetings, including:

• paediatric and adult congenital joint cardiology cardiothoracic (JCC)
• paediatric respiratory
• national pulmonary hypertension service (NPHS)
• paediatric intensive care imaging.

Dr Thomas Semple has a variety of expertise in heart and lung procedures and services including:

• childhood interstitial lung disease (ChILD) imaging
• magnetic resonance imaging (MRI) of lung disease
• CT imaging for congenital heart disease assessment (adult and paediatric)
• Lymphatic imaging, including fluoroscopic, CT and MRI lymphangiography
• Cardiac CT imaging, including coronary, valve assessment, procedural planning including valve intervention (melody, TAVI, TMVI), left atrial appendage device planning and electrophysiology procedural planning
• Paediatric cardiac intensive care ultrasound – specifically cranial doppler and central and peripheral vascular ultrasound
• General paediatric imaging, thoracic imaging and thoracic intervention (adult and paediatric biopsies and drain insertions).

Dr Thomas Semple’s research interest include:

• paediatric lung imaging (including structural and functional lung MRI)
• use of cardiac CT techniques in paediatric practice including neonatal coronary CT.

Dr Thomas Semple has published in topics covering paediatric and adult, cardiac and respiratory imaging. He has contributed to recent editions of textbooks including Kendig’s disorders of the respiratory tract in children and Grainger and Allison’s Diagnostic Radiology.

Dr Semple regularly speaks at imaging courses and international and national meetings. He also regularly supervises rotating registrars and Imperial College BSc students both in their day-to-day work and at scientific meetings.
