Sarcomas are tumors of mesenchymal origin that are generally resistant to systemic therapies and prone to local recurrence despite current multimodal treatment approaches. Focused ultrasound (FUS) is a noninvasive therapeutic technology that may enhance standard treatment strategies for primary solid malignancies. FUS exerts its effects through diverse mechanisms, including high-intensity focused ultrasound (HIFU) thermal ablation, histotripsy, sonodynamic therapy, immunomodulation, and hyperthermia-enhanced drug delivery. In this narrative review, we summarize the mechanisms of focused ultrasound that have been investigated for the treatment of sarcomas and highlight the results of preclinical, veterinary, and clinical studies related to this area.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
