Overview

There are no echocardiography/ultrasound findings associated with [disease name].

OR

Echocardiography/ultrasound may be helpful in the diagnosis of [disease name]. Findings on an echocardiography/ultrasound suggestive of/diagnostic of [disease name] include [finding 1], [finding 2], and [finding 3].

OR

There are no echocardiography/ultrasound findings associated with [disease name]. However, an echocardiography/ultrasound may be helpful in the diagnosis of complications of [disease name], which include [complication 1], [complication 2], and [complication 3].

Transabdominal Ultrasound

  • Ultrasound may be helpful in the diagnosis of insulinoma. The senstivity varies from 0-66%. Smaller tumor are difficult to detect especially those on pancraes tail. Findings on a transabdominal ultrasound suggestive of insulinoma include[1]
  • An ultrasound may be helpful in the diagnosis of complications of malignant insulinoma, which include:

Invasive Ultrasound

Endoscopic Ultrasound

This is an invasive ultrasound which can be done pre-operatively. The use has been increased with the increase in senstivities from 40-93%, more accurate in pancreatic head insulinomas. It is supported as the primary diagnostic modality for the diagnosis of pancreatic neuroendocrine tumors (whcih includes insulinoma) [1] [2][3]

  • It enables visulization of smaller tumors (2 mm)
  • Local metastasis can be detected

Laparoscopic Intra-operative Ultrasound

The use was introduced in 1981 and used to localise non-palpable lesions and those who are in close proximity to pancreatic and bile ducts. They can localise the tumors in 86% of cases when performed during an open or laproscopic surgery. [4][5]
