Selected AbstractsRadiographic herald lesion of the urinary bladder: Pictorial essayJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 3 2000Michael E Flisak SUMMARY At cystoscopy a focal mucosal abnormality may be indicative of a pathological process extrinsic to the urinary bladder and has been termed ,the herald lesion'. The aim of the present pictorial essay was to describe the radiographic counterpart to this cystoscopic finding. Radiographic herald lesions are shown in patients with extravesical inflammatory (Crohn's disease, colonic diverticulitis and pelvic inflammatory disease) and neoplastic (colon carcinoma) processes, and urinary tract complications of these conditions are described and illustrated. [source] Hypotonic duodenograms of postbulbar duodenal lesions: Pictorial essayJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 3 2000Yukiharu Sumi SUMMARY General features are described and examples are provided of the radiological manifestations of postbulbar duodenal lesions, particularly the findings on hypotonic duodenograms. Hypotonic duodenography does not always reveal the characteristic findings of postbulbar duodenal lesions, but it helps to evaluate luminal stenosis and diagnose disease entities even in lesions that show non-specific findings. Radiologists should be familiar with the radiological findings of postbulbar duodenal lesions and know which kinds of lesions can affect the postbulbar duodenum. This is important in making a differential diagnosis and in preventing delays in diagnosis. [source] Atrial septal defects: Magnetic resonance and computed tomography appearancesJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 3 2009ETD Hoey Summary Atrial septal defects are associated with significant morbidity and mortality. Echocardiography is the first-line imaging modality, but MR and CT imaging can provide complimentary information, especially for the detection of associated anomalies and for assessing changes in the pulmonary vasculature. The aim of this pictorial essay is to review the spectrum of atrial septal defects, with particular reference to their cross-sectional imaging appearances and issues pertaining to management. [source] Imaging of the haemorrhagic complications of the haemophiliasJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 1 2009S Constantine Summary Haemorrhage is the main manifestation of the haemophilias. Although acute haemorrhages can be life threatening, especially if involving the central nervous system, repeated haemorrhages involving the musculoskeletal system lead to two conditions unique to patients with haemophilias. This pictorial essay reviews the typical imaging appearances of haemorrhages and consequences in those with haemophilias, with particular emphasis on haemophilic arthropathy and pseudotumours. [source] Multidetector CT pulmonary angiography features of pulmonary embolusJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 4 2008JK Hoang Summary Pulmonary embolism (PE) is a life-threatening condition. Multidetector CT pulmonary angiography is currently the imaging method of choice for the detection of PE. The aim of this pictorial essay is to review the appearances of PE on multidetector CT pulmonary angiography, including signs that differentiate acute and chronic PE and markers of severity. The features of a non-diagnostic study and pitfalls leading to a false-positive or false-negative study are presented. [source] Unusual causes of small bowel obstruction and contemporary diagnostic algorithmJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 3 2008OG Gümü Summary Intestinal obstruction is a common clinical abnormality. In 60,80% of cases, the small bowel is affected. Although postoperative adhesions are responsible in 60% of cases, the other frequently observed causes are hernia, strangulation and tumours, such as carcinoid, lymphoma or adenocarcinoma. In this pictorial essay, we presented the radiological findings of uncommon causes of small bowel obstruction as well as the suggested diagnostic algorithm. [source] Imaging of painful solitary lesions of the sacrumJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 6 2007WCG Peh Summary In patients with sacral pain, the painful symptoms may be caused by a variety of bony and soft tissue lesions. Benign lesions include giant cell tumour, neurogenic tumour, insufficiency fracture, infection and giant bone island. Malignant lesions include primary bone tumours, Ewing sarcoma, plasmacytoma, lymphoma and chordoma. Soft tissue tumours adjacent to or involving the sacrum may cause painful symptoms. A multimodality approach to imaging is required for full assessment of these lesions. This pictorial essay describes a range of common solitary sacral lesions that may cause pain, with emphasis on imaging features. [source] Magnetic resonance imaging of ankle tendons and ligaments: Part I , AnatomyJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 4 2007A Kong Summary Magnetic resonance imaging is an excellent technique for imaging the tendons and the ligaments of the ankle. Owing to the advantage of detailed demonstration of soft-tissue structures and capability for multiplanar demonstration of the ankle ligaments and tendons, MRI has been increasingly used in the evaluation of the ligamentous and the tendon injuries of the ankle. Knowledge of normal anatomy and of MRI appearances are essential to recognize pathological appearances. In this pictorial essay, the first of a three part series, we review the normal MRI appearances of the ankle tendons and ligaments. The anterior, lateral and medial tendon groups, the Achilles tendon and the lateral, the syndesmotic and the medial ligament groups are described and illustrated. Anatomy of the sinus tarsi is also described. Tendon and ligament pathology will be illustrated in the second part of the series, and imaging approach to ankle injuries will be outlined in the final part of this series. [source] Computed tomography manifestations of peritoneal diseasesJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 4 2005K Gordon Summary The peritoneal cavity is a potential space that is divided by the peritoneal reflections into various complex subspaces. It can be involved in many disease processes including developmental, inflammatory, neoplastic and traumatic conditions. Computed tomography is highly sensitive and consistent in detecting peritoneal pathology. This pictorial essay aims to emphasize and illustrate the CT features of the spectrum of peritoneal diseases. [source] Radiological manifestations of malignant pleural mesotheliomaJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 2 2003Virginia WK Au Summary Malignant pleural mesothelioma has had a rising incidence in Australia over the past 40 years. This pictorial essay gives a brief account of the condition, summarizes the various radiological manifestations and aims at increasing the awareness of a disease that is expected to reach its peak incidence in the early decades of the twenty-first century.

Diffuse liver diseases in neonatal and pediatric liver transplant candidates: a pictorial essay. Clin Transplant 2010: 24: 450,458. © 2009 John Wiley & Sons A/S. Abstract:, A wide spectrum of common and uncommon diffuse liver diseases affecting neonatal and pediatric liver transplant candidates is presented and analyzed using 16 and 64 multi-detector row helical CT (MDCT) and 1.5 T MRI fast imaging. Correlation of imaging findings and explanted liver or histology is illustrated in representative cases. Associated uncommon congenital anomalies are shown. In conclusion, in pediatric liver transplant candidates, 16-MDCT and 1.5 T fast MRI are useful for diagnosis and staging of liver disease, as well as for the evaluation of associated congenital anomalies.
