Shoulder pain is one of the most common musculoskeletal complaints in clinical practice. Ultrasonography is a useful method for the diagnosis of various shoulder diseases and injuries. This article presents the ultrasonographic features of common shoulder conditions, including those affecting the rotator cuff, long head of the biceps, subacromial-subdeltoid bursa, and glenohumeral and acromioclavicular joints.

Splenic tuberculosis is known to occur due to hematogenous spread from the affected lungs. Ultrasonography shows non-specific features, including hepatosplenomegaly or abscess. Possible small hypoechoic nodules or larger hypoechoic mass-like areas are also observed. Sometimes it is challenging to differentiate splenic tuberculosis from a splenic pyogenic abscess. An 85-year-old man visited our clinic with abdominal discomfort and fatigue. He had a history of antituberculous medication. Upper abdominal ultrasonography showed an about 5 cm-sized pyogenic abscess-like lesion in the spleen. His symptoms and laboratory findings were not improved after a course of empirical antibiotic treatment. He was suspected of having secondary splenic tuberculosis and continued taking antituberculous medication. We are following up on his symptoms and radiologic images.

Ultrasound is essential for differential diagnosis in patients with left lower quadrant (LLQ) abdominal pain. Causes of LLQ pain are variable such as diverticulitis, colitis, appendagitis, and rarely appendicitis (in situs inversus). Colon cancer also is an occasional cause. Ultrasound findings of colon cancer are irregular wall thickening with loss of wall stratification and luminal narrowing. We report a case of descending colon cancer with hepatic metastasis detected on abdominal ultrasound in a 78-year-old female patient with LLQ pain. Ultrasound findings showed irregular bowel wall thickening with loss of wall stratification, luminal narrowing at the descending colon, and multiple hyperechoic nodules with peripheral halo at S4, 7, and 8 of the liver.

Microvascular imaging is a new ultrasound technique aiming to image and quantify the microvasculature, comprising arterioles, venules, and maybe even capillaries. The technique uses an advanced clutter filter to eliminate artifacts caused by breathing and movement and retains the low-speed blood signals in microvessels. The great advantage of microvascular imaging in ultrasonography is that it allows a physician intuitively to detect very slow blood signals in microvessels, providing additional information about flow distribution in the target area without the use of contrast media. This technical advance in ultrasonography will improve diagnosis in various clinical situations. In this review, we focus on microvascular imaging in the liver.

Ultrasonography is a simple and safe medical tool for diagnosing thyroid nodules and evaluating malignancy. National Health Insurance coverage for ultrasonography was implemented in Korea, and coverage for thyroid ultrasonography has been in effect since 2016. In 2022, with expanded coverage, imaging standards for reimbursement were recommended. The diagnosis of thyroid nodules will be discussed in this article based on updated reimbursement criteria and recommended standard imaging.

Today, echocardiography is an essential non-invasive diagnostic imaging tool used in clinics worldwide. However, the application of ultrasound to the heart began only about 70 years ago. In the early 1950s, Hertz and Edler described the use of ultrasound for myocardial walls and mitral valve diseases. Feigenbaum (1960s) expanded the clinical use of M-mode echocardiography. The advent of two-dimensional (2D) echocardiography (1970s), spectral Doppler (1970s), and color Doppler (1980s) established them for routine assessment of cardiac anatomy and hemodynamics. In Korea, the history of 2D echocardiography spans only 46 years, within living memory, and some early contributions are often overlooked. The initial 2D imaging using mechanical sector scanning was very different from the current electronic phased-array scanners. This review explores the historical status and actual images of the initial 2D echocardiography in Korea in 1977-1981.

Endoscopic ultrasonography is usually used in the diagnosis of subepithelial tumors but requires special equipment and expertise, which can be obstacles in some clinics. Transabdominal ultrasonography is an easily available diagnostic tool for diagnosing gastric subepithelial tumors. Hydroultrasonography can depict all five layers of the stomach wall. On ultrasonography, the gastric lipoma is recognized as a well demarcated hyperechoic mass mainly located in the submucosal layer. The ectopic pancreas is recognized as a well-demarcated, oval, heterogeneous, hypoechoic mass mainly located in the mucosal and submucosal layers. We diagnosed a lipoma and ectopic pancreas via abdominal ultrasonography after the patient drank water.

Gout is a representative inflammatory arthritis with an increasing incidence in recent years. Gout may be accompanied by a chronic course in which sodium urate crystals are continuously deposited to form gout nodules if proper uric acid management is not performed after acute symptom onset. In the past, an invasive method was applied to diagnose gout, but the development of various imaging modalities has prompted attempts to diagnose gout with a non-invasive method. Among these, ultrasound examination is a patient-friendly examination, is relatively convenient to perform in an outpatient setting, and can be used for treatment evaluation. Therefore, in this thesis, the ultrasound findings of gout are investigated and applied to actual treatment.

The Zenker’s diverticulum is the most common diverticulum of the esophagus. It commonly occurs at the pharyngoesophageal junction that can appear in proximity to the thyroid gland. The food remnants or gas bubbles present in the diverticulum may mimic microcalcifications presented in papillary thyroid carcinoma on ultrasonography. Therefore, it is important to be able to differentiate between Zenker’s diverticulum and malignant thyroid nodule. The author reported a case of Zenker’s diverticulum mimicking a thyroid nodule in thyroid ultrasonography.
