Nano-sized shell-stabilized gas bubbles have applications in various fields ranging from environmental science to biomedical engineering. A resonant mass measurement (RMM) technique is demonstrated here as a new and only method capable of simultaneously measuring the size and concentration of buoyant and non-buoyant particles in a nanobubble sample used as a next-generation ultrasound contrast agent.

Although relatively rare, cardiac metastases represent a significant clinical challenge because of their impact on cardiac function and overall patient prognosis. This case presents a rare and atypical presentation of a patient with ventricular arrhythmia revealing a metastatic cancer in the heart. A 59-year-old man with lung cancer was admitted for chest tightness and episodes of syncope.

We present the case of a young patient with an apical cardiac mass exhibiting an anterior pseudonecrosis pattern on the electrocardiogram. Cardiac ultrasound revealed a hyperechoic mass infiltrating the apical wall. However, cardiac magnetic resonance ruled out signs of infiltration and demonstrated significant contrast uptake.

Background: Acromiohumeral interval (AHI) reversibility is used to evaluate whether superior humeral migration is fixed or flexible in patients with massive rotator cuff tears (MRCTs). AHI reversibility is measured as the difference in the AHI observed between standard and stress radiography. However, factors affecting AHI reversibility have not been studied in the existing literature.

Pericardial and cardiac masses in patients with established malignant neoplasms represent a diagnostic and therapeutic challenge. We present the case of a 66-year-old woman with history of myxoid liposarcoma of the left thigh who had an unexpected recurrence in the pericardium 12 years later.
