Overview

Our research in cardiovascular imaging focuses on the following main topics:

1. Coronary haemodynamics: Image based computer modelling of coronary artery disease and blood flow, clinical decision making in coronary artery disease and imaging to guide complex percutaneous coronary interventions
2. Pulmonary circulation: Novel image and data analysis approaches for better phenotyping and risk stratification for individuals with pulmonary vascular disease
3. Cardiac form and function: Cardiac imaging to better stratify patients with common cardiac disorders, develop non-invasive haemodynamic models for clinical applications and predict outcomes

Coronary Haemodynamics

Our focus is on analysis of invasive coronary angiogram images to better understand the limitation of blood flow to the myocardium produced by coronary artery disease. This feeds into our computational modelling work. It allows cardiologists to target their interventional therapies to lesions that matter, and reduce hazardous and unnecessary procedures. Our group also aims to develop a better understanding of the interface between coronary flow and myocardial ischaemia using first pass myocardial perfusion on MRI.  

Pulmonary Circulation

Our research ambition is to improve the management and outcome of patients with pulmonary vascular disease. We have ongoing projects that aim to:

1. Improve the diagnosis of pulmonary hypertension and determine disease severity
2. Better stratify patients in diagnostic categories: pulmonary arterial hypertension, pulmonary hypertension associated with left heart disease or lung disease and patients with chronic thromboembolic disease
3. Improve risk stratification to allow for better predictions of therapy response and 1 year mortality

Our research utilises data from the ; a large DICOM imaging repository with computed tomography (CT) and cardiac magnetic resonance (CMR) imaging scans in individuals with suspected pulmonary hypertension cases (>5000 cases).  We are developing and utilising machine learning approaches within the group and in collaboration with the Department of Computer Science, and other universities e.g Leiden Medical Centre.

Cardiac form and function

Our vision is to develop an optimal imaging approach for patients with several cardiovascular disorders. We aim to do this by utilising state-of-the-art imaging techniques like four-dimensional flow (4D flow) CMR. Also, we develop novel image analysis approaches to better stratify patients and make better predictions of their clinical outcomes. 

We have established a unique partnership with 91Ö±²¥ Teaching Hospitals through a joint venture called 3D lab. The 3D lab provides a wealth of clinical imaging with encoded clinically relevant data for informing patient outcomes in the real world. The 3D lab imaging database has a large repository of CMR and cardiac CT scans. In the long run, our vision is that this resource will provide access to carry out large observational studies exploring the value of clinical imaging. The main strengths of this database are that it records all imaging based segmentation data, which can be then investigated for patient outcomes. This database is also well integrated with other clinical databases at 91Ö±²¥ Teaching Hospitals. This pioneering collaboration between the University academics and the NHS is also supported by the technical expertise of the Medical Physics Department of 91Ö±²¥ Teaching Hospitals.
