Percutaneous ultrasound-guided sample collection is used to obtain needle aspirates and tissue core biopsy specimens for a more definitive diagnosis due to the non-specific nature of most ultrasound abnormalities. Common examples are hepatomegaly, diffusely hyperechoic liver, multifocal liver and splenic nodules. Increased echogenicity and nodules have many differential diagnoses from benign to malignant. While ultrasound is screens and identifies diffuse and focal and multifocal lesions, it is non-specific. Ultrasound-guided tissue sampling offers real-time visualization of needle placement for precise sampling of a selected portion
of an organ or a focal abnormality, such as a mass lesion. Common clinical indication in animals include evaluation of enlarged lymph nodes, masses nonspecific hepatopathies and splenic disease.
Patient selection and preparation
Animals should have a complete sonographic examination performed of the body region. Complete work up with blood work is also imperative and underlying coagulopathies should be screened for. Animals with coagulopathies should not have tissue sampling performed as a general rule.
Sedation is not always necessary and many animals can have the liver and spleen sampled with a fine needle aspirate without it. However, risk should not be taken and if the animal is not cooperative, painful or panting heavily, then sedation should be performed for FNA. On the other hand, sedation is always recommended for Tru-Cut biopsy sampling.
The approach to the organ should be investigated carefully. Check the probe position so that the needle has the shortest path between the skin and the lesion.
Never pass between two body cavities or another organ to sample the lesion or organ.
Typically, cavitary lesions can be sampled with FNA, but not a tru-cut biopsy. Solid parenchymal organs or lesions

4. Exposure
Publishing relevant content and having a strong brand are only useful if they are seen by local pet owners. Facebook Ads and offline marketing will help to build up the ‘Likes’ or potential audience of the page. Creating
a vibrant community and Facebook Ads will ensure people that like the page see important posts. Search Engine Optimisation will ensure that the practice is found when local owners are searching for a vet or for relevant content.
5. Measure
One of the joys of digital marketing is that its results are usually measurable. Defining the measurements that will be used as Key Performance Indicators should form part of the digital marketing strategy. These should be used to optimise and refine the approach on a regular basis, allowing your practice to be responsive to your client base and local communities.
