A novel ultrasonic method for evaluation of blood clotting parameters
ConclusionsOur results showed that during blood clotting, the ultrasound velocity and variations in frequency spectrum should be used simultaneously to determine the beginning and duration of blood clot retraction. Our results also showed that blood clot retraction is controlled by the activity of factor XIII. (Source: Journal of Medical Ultrasonics)

The effect of halogen light stimulation on duration of ultrasound parameters of biophysical profile: a randomized clinical trial
The objective is to assess if fetal halogen light stimulation can reduce the time needed to obtain a normal biophysical profile (BPP).MethodsPatients scheduled for a BPP and who satisfied the inclusion criteria were prospectively randomized to halogen light stimulation and no stimulation groups. The study group was exposed to handheld halogen light for 10  s whenever fetal breathing, movement, or tone was absent through the first 5 min of BPP. The time required to achieve complete BPP score was recorded. In patients with complete BPP score who had delivery within 1 week after the test, perinatal morbidity wa...

A case of stage IA pancreatic ductal adenocarcinoma accompanied with focal pancreatitis demonstrated by contrast-enhanced ultrasonography
AbstractA patient with slight dilatation of the main pancreatic duct was followed-up with ultrasonography every 6  months as a high-risk case of pancreatic cancer. Twelve years later, a faint hypoechoic area 13 mm in diameter was first detected on the body of the pancreas. Contrast-enhanced ultrasonography revealed a well-demarcated hypoenhanced area 8 mm in diameter and a hyperenhanced area with an unclear margin. The former was suspected to be a small pancreatic cancer lesion, and the latter to be focal pancreatitis accompanying cancer. However, contrast-enhanced dynamic CT did not suggest any tumor, diagn...

Ultrasonographic images of the hand in a case with early eosinophilic fasciitis
AbstractEosinophilic fasciitis (EF), a rare rheumatic disease, usually affects the limbs symmetrically and generally spares the hands and feet. Cases of unilateral hand involvement are rarely reported. Here, we report such a rare case. Ultrasonography demonstrated thickening of the overlying skin and subcutaneous tissue, peripheral deep fascia, myositis of lumbrical muscles and adductor pollicis muscle, and edema surrounding flexor digitorum tendons. It reminds us that EF should be considered in the differential diagnosis of unilateral painful hand swelling despite being uncommon. Ultrasonography can be used to aid the dia...

AbstractAcute funisitis is characterized by the infiltration of fetal neutrophils from the umbilical vessels into Wharton ’s jelly and presents as fetal inflammation. However, no reports about its prenatal diagnosis using ultrasonography have been published. We encountered one case of oligohydramnios at 26 weeks and another case of threatened premature delivery at 27 weeks of gestation with ultrasonographic finding s of non-uniform thickening of Wharton’s jelly, a heterogeneous internal echo, and a high echoic line of the umbilical vessel wall.

Usefulness of acceleration time ratio in diagnosis of internal carotid artery origin stenosis
AbstractPurposeThe acceleration time (AcT) ratio of the internal carotid artery (ICA) is increased in ICA stenosis. However, there are few reports that have directly compared the AcT ratio to digital subtraction angiography (DSA) findings.MethodsWe evaluated 177 vessels with DSA and carotid artery ultrasonography. The AcT ratio was calculated as AcT of the ICA (ICA –AcT)/AcT of the ipsilateral common carotid artery (CCA). We evaluated the correlation of DSA–NASCET stenosis with the origin of the ICA or the peak systolic velocity (ICApsv) in the stenotic region, ICApsv/peak systolic velocity of the CCA (CCApsv),...

Superb microvascular imaging (SMI) findings of splenic artery pseudoaneurysm: a report of two cases
AbstractSplenic artery pseudoaneurysm (SAPA) is a relatively infrequently encountered but clinically important vascular change, because it carries a high risk of rupture that warrants prompt treatment regardless of its size. Thus, sufficient knowledge is indispensable when seeing chronic pancreatitis patients or post-traumatic patients. Here, we report two such cases. The first case was a 52-year-old woman known to have chronic pancreatitis who presented with hematemesis and hemodynamic instability in which X-ray computed tomography (CT) and color Doppler sonography (CDS) had difficulty visualizing slow blood flow in SAPA,...

AbstractCardiac hemangiomas are rare benign tumors. Here, we report the case of a man in his 30s who had a cardiac hemangioma with no symptoms. He was being treated with β-blockers for chronic heart failure with hypertensive heart disease at Osaka Minato Central Hospital. Routine echocardiography revealed a mobile spherical mass in the left ventricle that had not been detected on echocardiography performed 4 months previously. Subsequently, the tumor was excised t o prevent potential embolic events and was pathologically diagnosed as a cardiac hemangioma. This case demonstrates the relatively rapid progress of a ...

Vascular ultrasound in pediatrics: utility and application of location and measurement of jugular and femoral vessels
ConclusionsIn pediatric patients, major vessels can be located and their depth and diameter measured by vascular ultrasound. In younger patients, jugular and femoral vessels had similar depth values; in older ones, they had similar diameters. Ultrasound measurements in pediatric patients could facilitate the choice of the vessel to be cannulated, the catheter diameter, and the length of the needle to be used. Vascular canalization of IJV may be recommended as the first choice because of its low depth and large diameter. (Source: Journal of Medical Ultrasonics)

Triphasic mitral inflow pattern associated with hemodynamic deterioration in anemia or mitral regurgitation: a report of two cases

Case 2 was a 72-year-old woman with severe mitral regurgitation d ue to ruptured chordae tendineae. Pulsed Doppler echocardiography showed an L wave that disappeared after mitral valve repair.

Development of pseudoaneurysm in cesarean section scar pregnancy: a case report and literature review
AbstractCesarean scar pregnancy (CSP) is a rare type of ectopic pregnancy. It is becoming more common, but it can lead to uterine rupture and severe hemorrhage. Here, we report a case of a 37-year-old woman with CSP complicated with pseudoaneurysm. The pseudoaneurysm emerged following focal injection of methotrexate (MTX) and potassium chloride with systemic MTX treatment. Due to a risk of sudden bleeding, uterine artery embolization (UAE) was recommended, but the patient hoped to avoid this if possible. Because the serum human chorionic gonadotropin level and the gestational sac were still persistent, dilation and curetta...
