  • This study was conducted to retrospectively evaluate the pattern of contrast enhancement with SonoVue on gray-scale ultrasonography of hepatic angiomyolipoma (HAML). Imaging features of 33 pathologically proven HAML lesions in 33 patients who underwent baseline ultrasound and contrast-enhanced ultrasonography (CEUS) were assessed retrospectively. All lesions were enhanced in the arterial phase and showed whole-tumor filling in. Thirty-two of 33 (97%) lesions showed early positive enhancement in the arterial phase. Twenty-three of these exhibited isoechoic or hyperechoic features in the portal phase. HAML demonstrate characteristic manifestations with SonoVue-enhanced real-time gray-scale ultrasonography.

  • This study was performed to evaluate the effect of acupuncture on gastric motility in dogs with radiography and ultrasonography. All experimental dogs were fed with the soup with barium (3% W/V), and thereafter gastric emptying time(GET) was measured with radiography and ultrasonography with Bolondi's method. The acupoints were CV-12, PC-6, ST-36 and BL-21 in this experiment. On these acupoints, electroacupunctral stimulation(15 MHz, continous wave) was applied for 20 minutes. The results were as follows: In the control group, normal GET was 70-85 minutes with ultrasonography, and 110-130 minutes with radiography. In acupuncture stimulation groups, there was no effect of gastric motility in CV-12, PC-6, and 57-36, whereas there was significant stimulating effect of gastric movement in BL-21 with ultrasonography (P < 0.05) and radiography (P < 0.01). Above these results, it is concluded that acupunctural stimulation of BL-21 was more effective in gastric motility compared to those of CV-l2, PC-6 and ST-36.

  • A 4-month-old 5.7 kg male Golden retriever with history of seizure, depression, lethargy and anorexia was referred to Veterinary Medical Teaching Hospital, Chungbuk National University. Hematologic examination revealed microcytosis and nonregenerative anemia. Serum chemical values showed increased serum ammonia (423 $\mu$mol/L), ALP (1101 U/L), r-GTP (13.9 U/L) and CPK (1454 U/L), and decreased total protein (4.9 g/dl) and BUN (1.6 mg/dl). Microhepatia was shown in survey abdominal radiographs. Color doppler ultrasonographic examination revealed dilated tortuous vein with turbulent flow within liver parenchyma. Intraoperative jejunoportography and intraoperative ultrasonography confirmed the location and size of single intrahepatic shunt vessel in the left medial liver lobe. Also, the anomalous vessel entering the caudal vena cava was identified beneath the diaphragm. The shunting vessel was ligated with using an Ameroid constrictor. General conditions, hematologic and serum chemical values resolved gradually after surgery. One month after surgery abdominal radiograph showed normal gastric axis and it was consistent whit the normal size liver. Normal echogenecity of liver and enlargement of portal vein were shown in ultrasonography. It is assumed that survey radiography and ultrasonography are useful for diagnosis of single intrahepatic shunt in a dog and especially jejunoportography vein portography and intraoperative ultrasonography are suitable for confirmation of the anatomic location and size of the shunting vessels.

  • Chronic postoperative inguinal pain (CPIP) is a major complication after inguinal herniorrhaphy. We report the treatment of CPIP using ultrasonography-combined with nerve stimulator for injection of the genitofemoral nerve (GFN). A 59-year-old man underwent laparoscopic herniorrhaphy and presented with numbness from the inguinal region to the scrotum after operation. In the pain clinic, ultrasonography-guided GFN block and pharmacological treatments had little effect. Six month after operation, patient was referred to the Department of Physical Medicine and Rehabilitation, and ultrasonography-combined with nerve stimulator for GFN injection underwent to enhance the accuracy of neural approach. The induction of scrotal contraction and paresthesia on the GFN distribution was monitored by nerve stimulator and local anesthetic was injected. After the block, pain relief lasted for 6 months without analgesic use. Ultrasonography-combined with nerve stimulator is an effective approach to treat CPIP as it enhances precise localization and injection of small peripheral nerve like GFN.

  • Myofascial pain syndrome (MPS) is a common musculoskeletal disorder characterized by muscle pain, tenderness, and trigger points. Ultrasonography has emerged as a key tool for diagnosing and treating MPS owing to its ability to provide precise, minimally invasive guidance. This review discusses the use of ultrasonography in various approaches to evaluate and manage MPS. Studies have shown that shear-wave sonoelastography can effectively assess muscle elasticity and offer insights into trapezius stiffness in patients with MPS. Ultrasound-guided interfascial hydrodissection, especially with visual feedback, has demonstrated effectiveness in treating trapezius MPS. Similarly, ultrasound-guided rhomboid interfascial plane blocks and perimysium dissection for posterior shoulder MPS have significantly reduced pain and improved quality of life. The combination of extracorporeal shockwave therapy with ultrasound-guided lidocaine injections has been particularly successful in reducing pain and stiffness in trapezius MPS. Research regarding various guided injections, including dry needling, interfascial plane blocks, and fascial hydrodissection, emphasizes the importance of ultrasonography for accuracy and safety. Additionally, ultrasound-guided delivery of local anesthetics and steroids to the quadratus lumborum muscle has shown lasting pain relief over a 6-month period. Overall, these findings highlight the pivotal role of ultrasonography in the assessment and treatment of MPS.

  • Closed reduction is the treatment of choice for most nasal bone fractures. In this technique, the nasal bone cannot be directly visualized, proper reduction is confirmed by palpation of the bony contour. This confirmation-via-palpation is in most cases too uncomfortable or painful for patients, and this is the reason why most closed reductions of nasal bone fractures are performed under general anesthesia. Recently, ultrasonography has been adopted as a useful diagnostic method and operative adjunct. In this report, we report the use of ultrasonography as a means to provide palpation-less confirmation of proper reduction, which in turn allows for nasal bone reduction under local anesthesia.

  • Transcranial doppler ultrasonography (TCD) is a new, non-invasive and easily applicable method to evaluate cerebral hemodynamics. Last 10 years, its use in Korea has been dramatically expanded, but the qualification of TCD laboratory has yet to be settled. Since duplex sonography is seldom used in Korea, we have to depend totally on TCD to evaluate cerebral hemodynamic changes. Thus, all of the available data from every detectabler cerebral arteries has to be obtained for accurate interpretation of TCD measurements. Moreover, flow direction and wave form should be concerned in addition to the flow velocity. In this article, I present technique to measure the anterior, meddle and posterior cerebral arteries, the internal carotid artery siphon and at cervical level, and the vertebral and the basilar artery, and normal values for these measurements which is essential for the adequate interpretation.
