Head and neck ultrasound is a typical radiological exam played at so much hosp itals. it's a tremendous subject and all expert registrars in radiology might want to easy methods to experiment the organs and constructions of the top and neck. This booklet covers common anatomy and offers a finished account of pathological strategies in all the head and neck constructions, together with the vasculature. With very good diagrams and prime quality photographs, it illustrates the major technical and diagnostic steps wanted by means of either trainee and validated radiographers or radiologists. It presents transparent tips on scanning procedure, capability pitfalls and customary difficulties, and the way to accomplish optimal photo caliber. Key themes comprise: basic anatomy of the top and neck zone, sensible scanning strategy, the salivary glands, the thyroid and parathyroid, lymph nodes, cystic lots, the larynx, what the physician must understand and why, biopsy innovations and easy vascular ultrasound.

One essential piece of equipment is a high quality, adjustable and mobile table. It is important that for US and US guided procedures in the neck, the examiner is comfortable. A mobile table that can be easily positioned so that the patient's neck is level with the US monitor and within the operators scanning range is essential. Most operators find the most comfortable position to be, one in which the patient's neck is level with the examiner's thigh or knees. When carrying out biopsy techniques the operator must be positioned so that the monitor can be viewed comfortably without undue stretching or twisting.

Ductal stones can be identified if one remembers that the main duct continues approximately one finger breadth below the zygomatic arch until it pierces the buccinator muscle, and scanning should take place in this plane.
