Cardiac imaging guru Dr. Stephan Achenbach from Erlangen, Germany, contributed one of the daily quizzes posted by the European Society of Cardiology (ESC) during this week's annual congress in Barcelona, Spain. Achenbach was chair of the congress program committee at ESC 2017, which concluded on 30 August.
Members of the European Association of Cardiovascular Imaging (EACVI) created the short quizzes. Below, you can test yourself to see if you can give the correct diagnosis in all four cases.
Quiz 1

Three-dimensional CT angiography of the heart in a 53-year-old patient with shortness of breath.

Quiz 2

A 67-year-old male patient was referred for assessment of viability following recent acute myocardial infarction. A still frame of a midventricular short-axis cine (left) and a late gadolinium-enhanced MRI scan in the same orientation (right) are shown.

Quiz 3

Cardiac late-enhancement MR image in an 80-year-old female with shortness of breath, concentric left ventricular hypertrophy and severe diastolic dysfunction.

Quiz 4

Transthoracic echocardiography (modified four-chamber view) in a 42-year-old female with atypical chest pain and stress electrocardiogram (ECG), suggesting myocardial ischemia. The arrow points at an unusual structure in the right ventricle.

![Examples of ultrasound findings and techniques. (A) Images in a 39-year-old male patient with a mass in the left thigh. The mass is heterogeneous on the B-mode US image (compared with the patient in D) and showed increased microvascularity (superb microvascular imaging [SMI]) and shear-wave elastography (SWE) values. Undifferentiated pleomorphic sarcoma was diagnosed at biopsy (with pleomorphic rhabdomyosarcoma in surgical specimen). (B) Images in an 18-year-old male patient with a mass in the left leg. The mass is hypoechoic on the B-mode image, with no other findings suggestive of malignancy. The lesion is in contact with the cortex of the tibia, which is slightly irregular. CT revealed a doubtful anteromedial tibial erosion. The microvascular study demonstrated high vascularization, suggestive of malignancy. Periosteal Ewing sarcoma was diagnosed with both histologic and immunohistochemical confirmation. (C) Images in a 69-year-old female patient with a lump growing on the outside of the left leg. Multiple SWE examinations were performed (please note the high values obtained in the measurements, whereas the color map highlights the stiffness relative to adjacent tissues). SMI showed areas of increased vascularization to target for sampling. Undifferentiated spindle cell sarcoma was diagnosed at biopsy, with residual leiomyosarcoma in the surgical specimen after neoadjuvant therapy. (D) Images in a 56-year-old female patient with a mass in the right thigh. The mass is heterogeneous at both B-mode ultrasound (similar to patient A) and MRI (coronal T2-weighted spectral attenuated inversion recovery [SPAIR]; T1-weighted pre-contrast and postcontrast imaging), which even shows uptake after the administration of paramagnetic contrast material, which is traditionally suggestive of malignancy. Low values at SMI and elastography are suggestive of benignity. Spindle cell lipoma was diagnosed at biopsy, with atypical spindle cell lipomatous tumor in the surgical specimen.](https://img.auntminnieeurope.com/mindful/smg/workspaces/default/uploads/2026/08/images-radiol250278fig2.APCFLSvX6p.jpg?auto=format%2Ccompress&fit=crop&h=100&q=70&w=100)
