RESUMO
Contrast enhanced ultrasonography enables dynamic evaluation of the microvasculature down to the capillaries when using high resolution ultrasound probes. It's application in the evaluation of axillary lymph nodes in breast cancer patients with clinically negative axilla has been studied in 42 patients. The results of pre operative CEUS evaluation was correlated with histopathology status of axillary nodes after the harvesting of nodes during modified radical mastectomy or sentinel node biopsy. Heterogeneous enhancement with micro bubbles of the axillary nodes was found to be the most distinguishing criteria for malignant nodes.

The term "acute mesenteric ischemia" (AMI) refers to a set of conditions where the blood supply to various segments of the small intestine is cut off, causing ischemia and subsequent inflammatory changes that might result in bowel gangrene. Estimates place the incidence between 0.09% and 0.2% of all acute surgical hospitalizations. Early diagnosis is essential, despite the entity being a rare cause of abdominal discomfort, because if left untreated, mortality is 50%. Herein, we present a case series of three patients with bowel ischemia following blunt abdominal trauma.
