Barium study associated with water siphon test in gastroesophageal reflux disease and its complications.

PURPOSE: The aim of this study was to evaluate the role of digital cineradiography associated with the water siphon test (WST) in the diagnosis of gastroesophageal reflux and to compare the results with oesophageal motility study, pH monitoring and endoscopy associated with biopsy and histology. MATERIALS AND METHODS: One hundred and sixty consecutive patients underwent digital cineradiography with WST, motility study, pH monitoring and endoscopy with biopsy. The presence of gastroesophageal reflux, oesophagitis, Barrett''s oesophagus and intestinal metaplasia was evaluated. RESULTS: WST vs. pH monitoring showed sensitivity of 71%, specificity of 31%, positive predictive value (PPV) of 53% …

Digital cineradiographic study of swallowing in infants with neurologic disease. Our experience

CT and MR imaging of chemotherapy-induced hepatopathy.

Chemotherapy-induced hepatopathy includes a wide variety of parenchymal and vascular hepatic changes on imaging, including diffuse or focal hepatopathies (i.e. hepatitis, steatosis, fibrosis, pseudocirrhosis, or sinusoidal obstruction). These changes can profoundly alter the hepatic parenchyma on imaging and result in both false negative and false-positive diagnoses of hepatic metastases and lead to errors in patient management strategies. It is therefore important for radiologists to have a comprehensive knowledge of the imaging patterns that may develop following chemotherapy. The purpose of this review is to explore the broad spectrum of hepatic parenchymal and vascular chemotherapy-indu…

Accuracy of the water-siphon test associated to barium study in a high prevalence gastro-oesophageal reflux disease population: a novel statistical approach

Summary Rationale, aims and objectives  Gastro-oesophageal reflux disease (GORD) is ‘a condition which develops when the reflux of gastric content causes troublesome symptoms or complications’. Instrumental diagnostic tests generally used for GORD are 24-hour pH-metry and upper gastrointestinal (GI) endoscopy but barium study associated with provocative manoeuvres such as the water-siphon test (WST), has also been used for GORD. The aim of this paper was to estimate the accuracy of several tests in patients with GORD in a tertiary care setting, focusing on WST, which is rapid and non-invasive, simple to perform and well-tolerated by patients. Method  A total of 172 consecutive patients, sym…

Dynamic Fast Imaging Employing Steady State Acquisition Magnetic Resonance Imaging of the Vocal Tract in One Overtone Male Singer: Our Preliminary Experience.

Summary Aims To demonstrate physiological changing of vocal tract's structures during overtone singing with commercial magnetic resonance imaging (MRI) Fast Imaging Employing Steady State Acquisition (FIESTA) dynamic sequence. Methods and Materials A 1.5 T MRI with a 16 channel head-and-neck coil and a FIESTA sequence were used. A temporal resolution of 0.155 sec (7 image/s). A single professional singer was studied. The MR acquisition is made while the singer performed a predetermined singing sequence. Three different overtone singing techniques were examined (L-technique, J-technique, and NG technique) and one effect (Ezengileer) applied to L-technique. For each overtone technique we eval…

Imaging of “Malignant” External Otitis

“Malignant” external otitis or necrotizing external otitis (NEO) is a rare and severe infection of the external auditory meatus, causing destructive changes of the petrous bone, infiltrating inframastoid and intracranial tissues, with potentially lethal consequences. Five male diabetic patients, aged 61 to 85 years-old (mean age was 74 y.o), referred with biopsy-proven NEO, underwent CT and MRI studies for the assessment of the extension of the disease. Clinical data concerning the examined patients are summarized in table 1. Contrast-enhanced MRI does not seem to help in differentiating granulation from neoplastic tissues, as both demonstrate inhomogeneous enhancement. In conclusion, NEO …

MRI findings in lingual venous malformations.

To describe the plain and enhanced MRI findings of lingual venous malformations and to discuss the importance of contrast medium in the differential diagnosis of high intensity lesions of the tongue on T(2) weighted images.The clinical records and MR images of eight patients affected by a lingual venous malformation were retrospectively reviewed. Patients presented with a palpable submucosal bluish-red soft mass in the tongue. MRI examinations were performed on a 0.5 T superconducting unit. Plain and enhanced SE (spin echo) T(1) weighted and FSE (fast spin echo) T(2) weighted images were acquired in axial, sagittal and coronal planes. Axial SPGR (spoiled gradient recalled echo) T(1) weighte…

Imaging of urinary bladder hernias

Lorenzo E. Bacigalupo1, Michele Bertolotto2, Filippo Barbiera3, Pietro Pavlica4, Roberto Lagalla3, Roberto S. Pozzi Mucelli2, Lorenzo E. Derchi1 Bacigalupo LE, Bertolotte M, Barbiera F, et al. erniation of the urinary bladder is not rare. It is usually considered that 1–3% of all inguinal hernias involve the bladder [1], and Iason [2], in 1944, reported an incidence of 10% in men older than 50 years. Most bladder hernias involve the inguinal and femoral canals, with the latter more frequent in women, and a predilection for the right side has been reported. However, herniations through ischiorectal, obturator, and abdominal wall openings have also been described. Any portion of the bladder m…
