We have four diagnostic modalities available for fast and accurate imaging : digital radiology (DR), ultrasound, fluoroscopy and computed tomography (CT). Each plays an important role in the management of patients with relative advantages and disadvantages. Radiology is fast and does not often require anaesthesia allowing vets to attain diagnoses during their emergency consultations. Radiology remains the backbone of orthopaedic surgery (bones and joints). Ultrasound allows us to look inside the abdomen and assess the organs such as the liver, spleen, kidneys and GIT and to see if there is any free fluid or enlarged lymph nodes. Fluoroscopy offers continuous imaging and can also be mobile to allow imaging during surgery. PESC has a 16 slice GE CT scanner which allows sensitive assessment of the brain, body cavities and spine.
