Multimodal Imaging for the Assessment of a Cardiac Mass - A Case of Primary Cardiac Sarcoma.

We present a case of an 85-year-old patient who underwent clinical work-up for chronic heart failure, acute coronary syndrome, and pulmonary embolism, until she was diagnosed with a cardiac mass that was histologically identified as sarcoma. The aim of this educational case report is to raise awareness of cardiac masses and to point out diagnostic hints towards a cardiac tumor on chest X-ray, coronary angiography, echocardiography, and chest CT. Moreover, the vital role of cardiac magnetic resonance for the diagnosis of a cardiac mass is highlighted.

Acute stroke: a comparison of different CT perfusion algorithms and validation of ischaemic lesions by follow-up imaging.

Objectives: To compare ischaemic lesions predicted by different CT perfusion (CTP) post-processing techniques and validate CTP lesions compared with final lesion size in stroke patients.

Methods: Fifty patients underwent CT, CTP and CT angiography. Quantitative values and colour maps were calculated using least mean square deconvolution (LMSD), maximum slope (MS) and conventional singular value decomposition deconvolution (SVDD) algorithms.
