Role of conventional ultrasonography in the diagnosis of gallbladder polypoid lesions
AbstractThe major role of conventional ultrasonography (US) can be divided into three processes: cancer screening, differential diagnosis, and assessment of the depth of tumor invasion. As US is a simple and minimally invasive modality, it is widely used for cancer screening and health checkups. Both gallbladder (GB) polyps and thickened wall of the GB are common US findings. On the contrary, US is prone to interference from gas echoes, and its diagnostic accuracy depends on both the US technology and the ability of sonographers. It is also important to be well acquainted with characteristic artifacts and how to manage the...

The contemporary role of echocardiography in the assessment and management of aortic stenosis
AbstractAortic stenosis (AS) represents a major healthcare issue because of its ever-increasing prevalence, poor prognosis, and complex pathophysiology. Echocardiography plays a central role in providing a comprehensive morphological and hemodynamic evaluation of AS. The diagnosis of severe AS is currently based on three hemodynamic parameters including maximal jet velocity, mean pressure gradient (mPG) across the aortic valve, and aortic valve area (AVA). However, inconsistent grading of AS severity is common when the AVA is

Characteristics of ultrasonographic images of ductal carcinoma in situ with abnormalities of the ducts
ConclusionDCIS cases with duct abnormalities on ultrasound were investigated in this study. The important characteristics were as follows: (1) the distribution of ductal dilatation was focal or segmental, (2) solid parts were present in the dilated ducts, (3) the distribution of internal echoes was continuous or multiple, (4) the shape of solid echoes was broad-based and/or irregular, and (5) internal echoes were sometimes accompanied by echogenic foci. Accurate evaluation of these findings may be useful for diagnosing DCIS. Although the duct abnormalities are included in “ASSOCIATED FEATURES” in ACR BI-RADS AT...

Endoscopic ultrasonography for the evaluation of pancreatic cystic neoplasms
AbstractEndoscopic ultrasonography (EUS) is a modality with high spatial resolution that enables comprehensive observation of the entire pancreas and plays an important role in the diagnosis of pancreatic lesions. Recent advances in diagnostic imaging methods such as ultrasound, computed tomography, and magnetic resonance imaging have increased the incidental detection of pancreatic cystic lesions (PCLs). EUS has been recognized as an essential diagnostic method for the detection and evaluation of PCLs. EUS has two important roles: as a detailed (high-resolution) imaging diagnostic method and as an approach for collecting ...

Echocardiographic assessment of mitral regurgitation
AbstractMitral regurgitation (MR) is one of the most frequent indications for valve surgery in developed countries, and echocardiographic assessment is an essential tool to evaluate its etiologies, severity, and therapeutic indications. The mitral valve apparatus is a complex structure composed of several parts: apart from the mitral valve leaflets and annulus, it also includes the chordae tendineae, papillary muscles, and left ventricular (LV) wall. MR can be caused not only by organic changes of the mitral valve leaflets or chordae (primary MR) but also by extreme mitral annular enlargement or mitral leaflet tethering du...

Endoscopic ultrasonography for pancreatic solid lesions
AbstractThe incidence and mortality rates of pancreatic cancer, which has a poor prognosis, are rising rapidly. Endoscopic ultrasonography (EUS) provides superior spatial resolution compared with other imaging modalities such as transabdominal ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI), and it is considered among the most reliable and efficient diagnostic modalities for pancreatic diseases. In this review, we show that EUS is useful for detection of pancreatic solid lesions and staging of pancreatic cancer. EUS also plays an important role in screening patients with high-risk factors for pan...

Common pitfalls and mistakes in pediatric ultrasound
AbstractThere are many errors and pitfalls that are commonly encountered during ultrasound examinations. In normal ultrasound, pitfalls may arise from anatomic or physiologic variants of pediatric anatomy, settings, artifacts, patient conditions, operator misunderstanding, or inexperienced performance. In limited field and point-of-care ultrasound, common errors are usually due to limited access, misdiagnosis as a result of wrong timing, unsuitable patient conditions, limited transducer options, satisfaction of search, and unfamiliarity with pediatric sonography. Knowledge of these pitfalls helps improve a physician &rsquo...

Ultrasonographic assessment of organs other than the heart in patients with heart failure
AbstractThe number of patients with heart failure has been dramatically increasing in Japan in association with aging of the society. This phenomenon is referred to as a heart failure pandemic. The fundamental origin of heart failure is cardiac dysfunction. Echocardiography is widely used to assess cardiac function, as well as to diagnose heart diseases that cause cardiac dysfunction. However, the severity of heart failure is not necessarily correlated with that of cardiac dysfunction. This is partly explained by the fact that heart failure induces dysfunction of organs other than the heart through hemodynamic deterioratio...
