Axillary arch: detailed ultrasonographic images with multiplanar CT correlation
We report the first detailed presentation of the ultrasonographic features of the axillary arch and a correlation of these findings with multiplanar reformation CT images incorporating a schematic anatomical diagram in a 44-year-old woman complaining of a palpable non-tender mass in the axillary region due to a unilateral axillary arch. The clinical significance of the axillary arch is discussed. (Source: Journal of Medical Ultrasonics)

Experimental system for in-situ measurement of temperature rise in animal tissue under exposure to acoustic radiation force impulse
Conclusion The developed system will become a useful tool for measuring in-situ temperature rise in animal experiments and obtaining findings with respect to the relationship between ultrasound irradiation conditions and in-situ temperature rise. (Source: Journal of Medical Ultrasonics)

Microscopic observation of glass bead movement in soft tissue-mimicking phantom under ultrasound PW mode scanning
Abstract Previous studies have demonstrated that stones and calcification in soft tissue show special enhancement in response to color flow (CF) or pulse Doppler (PW) mode ultrasound scan. This phenomenon is known as the “twinkling sign (TS)”. The authors conducted an in vitro experiment to investigate the mechanism of TS occurrence by observing a glass bead in a transparent PVA-H soft tissue-mimicking phantom. The TS in PW mode showed a low-power and slow-velocity spectrum. At the same time, analysis of images by high-speed camera showed that the glass bead in the phantom oscillated following the puls...

Benign nodular hyperplasia of the liver-pedunculated form: diagnostic contributions of ultrasonography and consideration of exophytic liver tumors
We present the case of a young female patient without a personal pathological history, who complained of intense, diffuse, intermittent, non-systematic abdominal pain and who underwent ultrasound examination, followed by contrast-enhanced ultrasound. With this technique, we evidenced a solid extrahepatic tumor, which was mobile at the patient’s change of position and had the hemodynamic features of FNH. The article also tackles the problem of intra-abdominal pedunculated tumors. (Source: Journal of Medical Ultrasonics)

Prenatal diagnosis of enterolithiasis at 18 weeks: multiple foci of intraluminal calcified meconium within echogenic bowel
Abstract Enterolithiasis is an uncommon finding of a dilated hyperechogenic bowel with multiple ball-like echogenic structures at a routine prenatal check-up using ultrasonography. We here report a case of prenatally diagnosed enterolithiasis at 18 weeks of gestation, showing multiple hyperechogenic foci rolling within the bowel fluid after peristalsis. The size of the dilated bowel gradually increased during pregnancy. Magnetic resonance image demonstrated the dilated lower bowel with blind-ending rectum. A postnatal contrast medium study with retrograde urethrography revealed a middle imperforate anus and a...

Combination of ultrasound and newly synthesized magnetic nanocapsules affects the temperature profile of CT26 tumors in BALB/c mice
Conclusion Data presented in this study would be helpful to develop an ultrasound-mediated MDT procedure so that temperature changes of the tumor and its surrounding normal tissues may be controllable. (Source: Journal of Medical Ultrasonics)

Prenatal diagnosis of type 1 fibular hemimelia
Abstract Fibular hemimelia (FH) is a congenital longitudinal limb deficiency characterized by complete or partial absence of the fibula. Typically, it has been diagnosed at birth, when the neonate is seen to have lower limb shortening and a foot with missing toes. Although it is the most frequent lower limb deficiency anomaly, there are few published reports of prenatally diagnosed cases. Most of these published cases have involved the complete absence of the fibula, which is relatively easy to diagnose with antenatal ultrasound. In our opinion, our case is the first case of unilateral partial absence of the fibul...

Characteristic sonographic features of cribriform papillary thyroid carcinoma for differentiation from other thyroid nodules
Conclusion The criteria for suspecting CV-PTC we proposed provided high sensitivity and specificity. We should be aware that the sonographic findings of CV-PTC are similar to those of follicular tumor or nodular goiter rather than C-PTC. Clinical findings including gender, age, and serum thyroglobulin level may provide us with useful information. (Source: Journal of Medical Ultrasonics)

Prenatal diagnosis of Klippel–Trenaunay–Weber syndrome with Kasabach–Merritt syndrome in utero
We present a prenatally diagnosed case of KTWS complicated with Kasabach-Merritt syndrome in utero and fetal hydrops from acute anemia. The fetus was diagnosed with KTWS at 24 weeks of gestation based on the ultrasound findings of hemangiomas and unilateral hypertrophy of the lower extremity. Acute enlargement of the hemangiomas and the appearance of new retroperitoneal hemangiomas were detected at 27 weeks, along with skin edema and cardiomegaly. Doppler examination showed elevated peak systolic velocity in the middle cerebral artery, indicating acute fetal anemia. We believe the fetus’s condition was comp...
