Current Concepts

Veterinary magnetic resonance imaging (MRI) is a well-established and highly valued tool for the evaluation of neurologic disease in dogs and cats due to its unrivaled ability to distinguish normal and abnormal soft tissues (known as tissue contrast). However, this same exquisite sensitivity of MRI for detecting lesions in the brain and spinal cord can be of great benefit when evaluating other organ systems and diseases. Continue reading

The literature suggests that ultrasound detects a primary pancreatic lesion in approximately 50% of cases and detects metastases in only 20% of cases.  CT has a reported success rate of detecting a primary lesion in 70% of cases, but is of limited value in the detection of metastases.
