Hungarian Radiology - 2003;77(06)

[INTRODUCTION - The injury of fixed bowel loops occurs more frequently due abdominal trauma. Authors review the CT signs of bowel injury in conjunction of the presented case. PATIENTS, METHODS - The inguinal hernia of the male patient was present for approximately 30 years prior the abdominal trauma. Due to the trauma the fixed small bowel loop became perforated. CT examination, beside using the conventional methods established the diagnosis of bowel wall perforation and the site of the perforation was localized before surgery. CONCLUSIONS - CT provied additional information compared to X-ray and US in the localization of the lesion due to the blunt abdominal trauma.]

[Comparison of different gastrointestinal contrast materials for MR examination, an experimental model]

BABOS Magor, PALKÓ András, KARDOS Lilla, CSERNAY László

[PURPOSE - Evaluation of different gastrointestinal endoluminal contrast materials by using an experimental model. MATERIALS AND METHODS - Authors constructed a plastic container holding six plastic cups, thus making possible to evaluate different compounds and concentrations, simultaneously. The signal intensity of more than 15 different materials (commonly used contrast materials, fruit juices, cocoa, iron containing solutions) was measured by T1 and T2 weighted spin echo sequences in a 1T MR unit. The results were compared in tables and demonstrated by figures. RESULTS - The plastic container and cups made it possible to evaluate the contrast materials by MR examination. The fruit juices containing metallic components had high signal intensity on T1 weighted images, while on the T2 weighted images showed moderate to high signal intensity except the rosehip syrup and a special blackcurrant extract, which were of low signal intensity. Cocoa drink had low to moderate signal intensity on both the T1 and T2 weighted images. The signal intensity of the iron(III)-desferrioxamin solution increased on the T1 weighted images and decreased on the T2 weighted images in direct proportion to its iron concentration. CONCLUSION - The described in vitro model is an appropriate and risk-free solution for selecting the proper endoluminal contrast material, its concentration, and the best measuring sequences for defining the optimal in vivo MR bowel examination protocol. On the base of the experimental results rosehip syrup, blackcurrant extract, iron(III)- desferrioxamin and cocoa drink were selected for further in vitro and in vivo examinations.]

[Navigation for image-guided procedures: a new modality and review]


[Basic principles of two types of medical navigation are discussed. In patient-based navigation (PBN) image acquisition is followed by intervention. In modality-based navigation the imaging modality is present in the operation room, and a reference system is used. Advantages and disadvantages of both navigation types are listed. The steps of an interventional procedure with a new navigation system are described and illustrated. The role and possible future trends of navigation are finally summarized.]

[Isolated gallbladder rupture following blunt abdominal trauma]


[INTRODUCTION - Gallbladder injuries following blunt abdominal trauma occur rarely and are usually associated with damage to other abdominal organs. Isolated rupture of the gallbladder is extremely rare. CASE REPORT - A 42-year old intoxicated male patient suffered a blunt abdominal trauma 4 days before the admission. The physical examination was of normal and no specific laboratory values were found. Ultrasound examination demonstrated the gallbladder with hyperechoic thickened wall and inhomogenous content. Beside of the gallbladder fluid collection was detected with irregular margins. To prove the diagnosis of gallbladder injury computed tomography was carried out. Break of the gallbladder wall and hight density lumen content, corresponding to blood was detected. Around the gallbladder an irregular fluid collection was seen, which reached the level of the transverse section of the mesocolon. Computed tomography excluded traumatic lesion of other parenchimal abdominal organs. Surgery confirmed the radiological diagnosis. CONCLUSION - The patient with isolated gallbladder injury had a multiphasic clinical course. Sometimes the diagnosis has to be established at a relatively asymptomatic stage. The basic methods of the diagnostics are the ultrasound examination and computed tomography.]

[Xanthogranulomatous cholecystitis]


[INTRODUCTION - The xanthogranulomatous cholecystitis is a rare and benign form of lesions associated with diffuse thickening of the gall bladder wall. It is important to recognize it radiologically because it can be mistaken easily for gall bladder carcinoma. The characteristic US, CT and MR findings, however, may be helpful in the differential diagnosis. CASE REPORT - We present the cases of two middleaged female patients suffering from right upper quadrant, radiating abdominal pain for several weeks without occurrence of fever. In both patients, the ultrasound examination revealed marked thickening of the gall bladder wall containing hypoechoic nodules. Further, non-specific sign such as cholecystolithiasis and fine infiltration of the adipose tissue surrounding the gall bladder and dilatation of extrahepatic or intrahepatic bile ducts were visible. On the post contrast CT images, rim enhancement was detectable. MR/MRCP examination showed a sharp delineation of the gall bladder from the liver parenchyma. Both patients underwent cholecystectomy. The pathological examination excluded malignancy and confirmed the diagnosis of xanthogranulomatous cholecystitis. CONCLUSION - The characteristic features of xanthogranulomatous cholecystitis (hypoechoic xanthogranulomas in the markedly thickened gall bladder wall and the presence of calculi) can be detected by ultrasound examination. CT or MRI may play an important role in confirmation of the diagnosis of an inflammatory process and provide useful information in exclusion of gall bladder carcinoma.]

[Dual energy computed tomography - dual-source CT]


[The authors describe fundamentals of computed tomography (CT) examination performed by dual-source, dual energy CT scanner. The special applications of dual energy acquisition are demonstrated, e. g. examination of pulmonary perfusion in case of embolism, bone subtraction during CT angiography, differentiation of various stones and calcifications. The dual energy acquisition can improve the accuracy and sensitivity of the radiological diagnosis.]

[Digital volume tomography - The use of cone beam CT in dentistry, oral and maxillofacial surgery]


[Oral and maxillofacial radiology is a subspecialty with its own field of indication. The goal is to achieve proper diagnostic image quality with the minimal amount of harmful radiation. The most common acquisition techniques are the intraoral radiograph and the panoramic radiograph which result in an overview picture of the whole dental status of the patient or the full mouth survey with the higher doses of radiation indicated for periodontological treatment. The next level is the supplementary radiograph such as occlusal radiograph, transversal tomography (some panoramic radiographs have this option), lateral cephalometric projection, submentovertex view or Waters projection, etc. More over cone beam CT acquisition or digital volume tomography as is called. In case of some described special indications CT, MRI or sometimes US acquisition can be made. In the field of three dimensional radio-diagnostics, the CT has a superior place with well-known advantages for everybody, and the usage has been limited only by the high radiation dose. The main point of the acquisition is the image quality. The load of radiation only makes the field of indication narrow. In every day practice - because of the higher radiation load of each high quality CT - the pictures passing to the doctor are preferred to take with lower resolution and wider slices although the diagnostic value of this never reaches the wanted level. This is why this new acquisition system also mentioned in the title would be better known. This system works with reasonable low radiation coupling with the possibilities of the high fidelity 3D imaging focusing on the bony structures of the head and neck region. The purpose of this article is to give a comprehensive introduction to this method in use for more than a decade. From 2006 in Hungary we also have the option to use the technology.]
