Soft tissue ultrasound: which areas are examined
Soft tissue ultrasound is designed to examine anatomical structures that are not part of the internal organs or the skeletal system. During the diagnostic process, the doctor assesses the morphological condition of the skin and the subcutaneous fat layer, and analyses the structure of muscles, tendons and ligaments. The method also allows for the examination of lymph nodes, determining their size and internal structure.
The examination may cover various areas of the body depending on the clinical objectives. In the face and neck region, soft tissue ultrasound is often used to monitor tissue condition following cosmetic procedures or to detect superficial nodules. Diagnostic examination of the anterior abdominal wall and back enables a detailed assessment of the integrity of the muscular framework and the homogeneity of adipose tissue. When scanning the limbs and gluteal region, the doctor examines the ligamentous apparatus and identifies the consequences of mechanical injuries.
Such a wide range of areas makes ultrasound scanning an informative tool for primary diagnosis. The method provides data on tissue structure, eliminating the need for invasive procedures.
Indications for soft tissue ultrasound: symptoms and complaints
The need for a soft tissue ultrasound is often prompted by the patient’s subjective complaints of changes in the subcutaneous structures or musculature. This method enables the doctor to quickly identify pathological processes hidden beneath the skin and determine their nature at an early stage.
The main indications for booking an examination are: Timely diagnosis allows the specialist to obtain an objective clinical picture and prevent inflammatory processes from becoming chronic. The use of ultrasound ensures high data accuracy, helping the doctor to select the most effective treatment plan or decide on the need for surgical intervention.
- lumps, nodules or growths under the skin;
- pain in muscles and soft tissues of unknown origin;
- persistent swelling or bruising;
- signs of inflammation (redness, throbbing, localised heat);
- monitoring of tissue condition following surgery.
What conditions does soft tissue ultrasound detect?
Ultrasound diagnostics helps to examine in detail what cannot be seen with the naked eye or simply felt by hand. During the examination, the doctor determines the exact location of the problem area, its size and its position in relation to neighbouring muscles or blood vessels. Based on this information, the specialist can determine the nature of the condition and the degree of risk to health.
The following groups of conditions are most commonly diagnosed during the examination: The data obtained enable the patient to be referred in a timely manner to a relevant specialist for treatment or surgical intervention. The informative value of the method, combined with its safety, makes ultrasound a key tool in the diagnosis of most soft tissue conditions.
Benign growths. Lipomas (overgrowth of fatty tissue), atheromas (sebaceous cysts), hygromas (fluid accumulation around joints) and fibromas, which consist of connective tissue fibres.
Purulent-inflammatory processes. An abscess — a focussed area of suppuration with clear boundaries — or phlegmon — extensive tissue inflammation without a clear outline. An infiltrate is also frequently detected, indicating the active stage of the inflammatory response.
Traumatic injuries. Haematomas of varying sizes, as well as complete or partial tears of muscles, ligaments and tendons resulting from impact or strain.
Hernias. Protrusion of internal organs due to defects in the muscular framework of the anterior abdominal wall (inguinal, umbilical or linea alba hernias).
How to prepare for a soft tissue ultrasound scan and what to expect
One of the main advantages of this type of examination is that no complex preparation is required. The patient may follow their usual diet, as eating or drinking does not affect the accuracy of imaging of superficial structures. Before visiting the clinic, it is recommended that you ensure the skin in the area to be examined is clean, wear comfortable clothing and remove any accessories that might hinder access to the area being examined.
The scan is carried out in conditions that are as comfortable as possible for the patient and does not cause any discomfort. At the start of the examination, the patient is asked to sit or lie down on the examination couch, having first removed any clothing from the area to be examined. To ensure close contact between the transducer and the body’s surface and to eliminate air pockets, the specialist applies a special hypoallergenic gel to the area being examined. During the scan, the doctor smoothly moves the probe in various directions, allowing for a detailed examination of muscle structure and the detection of any growths or signs of inflammation on the device’s monitor.
The entire process is completely painless and takes between 10 and 20 minutes, depending on the size of the area being examined and the complexity of the specific clinical case. Immediately after the examination is complete, any remaining gel is wiped away with a tissue, and the patient is given a copy of the examination report containing the measurement results and a description of the tissues. The method has no side effects, allowing patients to return to their normal daily routine straight away.
