    Abdominal ultrasonography as a health checkup has been considered to be useful for the early detection of cancer in abdominal organs such as the liver, pancreas, bile duct, kidneys, and so on. However, because of the lack of standardization of the procedure or assessment criteria, its effectiveness has not been evaluated objectively. In September 2011, the Guideline for Abdominal Ultrasound Cancer Screening was published by the Japanese Society of Gastroenterological Cancer Screening. This Guideline is composed of two chapters: Chapter 1, titled Standard Procedure for Abdominal Ultrasound Cancer Screening, and Chapter 2, titled Categorized Criteria for Abdominal Ultrasound Cancer Screening. With the collaboration of the Japan Society of Ningen Dock, the Japan Society of Ultrasonics in Medicine, and other related societies, the contents of the Guideline are being reviewed to make it perfect. The final goal of the Guideline is to evaluate the effectiveness of ultrasound screening in decreasing the number of cancer deaths.

    Plain radiograph, CT, and MRI are still often used to create images of the hand. However, these modalities have the same limitation: their images are all just still images. We, as orthopaedic surgeons, are doctors who examine the motor system such as muscles, bones, tendons, ligaments, and nerves. Therefore, it is very important for us to know about the clinical condition associated with motion. Recent advances in ultrasound devices and digital imaging have been remarkable, and recent high-resolution ultrasound devices have made it possible to create a clear image of superficial structures with a high-frequency probe. It would not be an exaggeration to say that ultrasonography could change the daily orthopaedic medical practice, and it is becoming more and more prevalent in the field of orthopaedics. In the field of hand surgery, most of the region of interest is located within 3 cm under the skin. It means that we could examine most of the region with one high-frequency linear probe. Here, we will present and explain the ultrasonograms from some of the clinical cases we often encounter at our hand clinic. Specifically, we will present cases of tenosynovitis, tendon injury, ligament injury, ganglion cyst, soft tissue tumor, fracture, rheumatoid arthritis, cubital tunnel syndrome, and carpal tunnel syndrome. Ultrasonography is useful not only for diagnosis but also for treatments such as nerve blocks, injections, or punctures. In addition, it is helpful as a communication tool between doctors and patients. In light of this fact, we think it will continue to develop more and more.

    We herein report a case of hypovascular renal tumor in which microvascular blood flow diagnosis by Sonazoid®-enhanced ultrasonography was possible. Abdominal ultrasonography (US) and magnetic resonance imaging (MRI) performed at another institution detected a left renal mass in a 75-year-old man with renal dysfunction. At our hospital, non-contrast computed tomography (CT) detected a mass at the same site. Staining was seen from the tumor margin to the interior of the tumor on contrast-enhanced ultrasonography using Sonazoid®. Therefore, malignancy was suspected, and translumbar partial nephrectomy was performed. The tumor was diagnosed as a papillary renal cell carcinoma based on histopathologic examination. In cases such as this in which contrast-enhanced CT is contraindicated, Sonazoid®-enhanced ultrasonography is useful for microvascular blood flow diagnosis of renal masses.
