The dynamics of leucocytes in abdominal abscesses were studied using indium-111 autologous leucocyte scanning in 30 patients. Thirteen patients showing enteric drainage of leucocytes on delayed scans were characterised by a lack of abdominal localising signs and a low detection rate by ultrasound (25%). By contrast, 16 of 17 patients without enteric drainage had abdominal signs, and in these pa...

A displaced Long Head of Biceps (LHB) tendon is commonly encountered in association with subscapularis rotator cuff tears. Management options for the displaced tendon consist of tenotomy, tenodesis or relocation with reconstruction of the biceps pulley. We present 16 patients in whom LHB relocation and reconstruction of the biceps pulley, was performed in association with subscapularis rotator ...

We developed an image processing chain as well as a related clinical workflow to reconstruct entire bone surfaces from 3D ultrasound volume data (see figure 1). A clinician acquires ultrasound images from relevant areas while scanning from various directions. The probe is tracked, the limb is equipped with non-invasive markers. The user is guided by a simple navigation interface in order to fol...

BACKGROUND Traditionally the radiological assessment of diaphragmatic movement has relied on fluoroscopy. Ultrasound scanning has recently been shown to be a sensitive and reproducible method of assessing hemidiaphragmatic movement in normal subjects. A study was undertaken to examine how movement of the diaphragm measured by ultrasound scanning relates to inspired lung volumes measured by spir...

BACKGROUND Recognition of the difficult airway is a critical element of emergency practice. Mallampati score and body mass index (BMI) are not always predictive and they may be unavailable in critically ill patients. Ultrasonography provides high-resolution images that are rapidly obtainable, mobile, and non-invasive. Studies have shown correlation of ultrasound measurements with difficult lary...

The impact of previous stillbirth, miscarriage, or preterm delivery on anxiety in pregnant women in various subgroups at high risk for fetal abnormality in comparison with a nonrisk control group of women with healthy uncomplicated pregnancies was studied longitudinally. The level of anxiety in women (n1⁄4674) during early pregnancy was assessed by questionnaire. Data were collected at three po...

We report here on the development of a fuzzy decision system to semi-automate ultrasonic prenatal examinations in order to reduce their cost, minimize exposure time of the fetus to ultrasonic radiation, and to provide a uniform examination for all patients. To our knowledge, this is the first successful application of its kind, and paves the way towards development of a computationally intellig...

OBJECTIVE To evaluate a self teaching approach to be followed by a novice without previous practical experience in musculoskeletal ultrasonography. METHODS The novice was given short general training (two hours) by an experienced sonographer focusing on the approach to the ultrasound equipment, and asked to obtain the best sonographic images of different anatomical areas as similar as possibl...

BACKGROUND Unstable carotid plaques on subjective, visual, assessment using B-mode ultrasound scanning appear as echolucent and heterogeneous. Although previous studies on computer assisted plaque characterisation have standardised B-mode images for brightness, improving the objective assessment of echolucency, little progress has been made towards standardisation of texture analysis methods, w...
