Aim: The aim of this study is to determine the impact of foot and ankle single-photon emission computed tomography (SPECT) CT on patient management.

Method And Materials: A retrospective review over a 7-year period investigating whether the study identified or confirmed a source of symptoms. The electronic patient record was reviewed to see whether the test was helpful to the onward management of the patient.

Computed tomography appearances of the lung parenchyma in pulmonary hypertension.

Computed tomography (CT) is a valuable tool in the workup of patients under investigation for pulmonary hypertension (PH) and may be the first test to suggest the diagnosis. CT parenchymal lung changes can help to differentiate the aetiology of PH. CT can demonstrate interstitial lung disease, emphysema associated with chronic obstructive pulmonary disease, features of left heart failure (including interstitial oedema), and changes secondary to miscellaneous conditions such as sarcoidosis.
