TL;DR: Multifocal gliomas are more frequent than generally believed and, therefore, multiple cerebral masses should be thoroughly evaluated and not always presumed to be of metastatic origin.

TL;DR: The association between mammographic parenchymal patterns and the risk of subsequent breast cancer was studied in a cohort of 17,911 women aged 40-70 years, enrolled in a mammographic screening program, and the adoption of a shorter rescreening interval is suggested.

TL;DR: It is suggested that transthoracic sonography can be an efficient technique in the detection of pulmonary infarction, as well in an early reperfusionable stage as in distinguished infarct formation.

TL;DR: The work presented here concerns the interpretation of multimodal 3D neuro-anatomical data bases and a review of up to date3D display techniques with a special emphasis on volume rendering and 3D display of combined data.

TL;DR: This work reviews and discusses different classes of image segmentation methods and classified these methods into (1) manual delineation, (2) low-level segmentation, and (3) model-based segmentation.

TL;DR: A classification of the existing multitude of cystic lesions of the brain is proposed, which allows an understanding of their genesis and consequent therapeutic implications, as well as their diagnostic characteristics.

TL;DR: Correlation with surgical or endoscopic findings showed that radiology depicted all single lesions, whereas multiple lesions were underestimated in one case, and experience indicates that enteroclysis is an effective means in evaluating patients with suspected benign small bowel tumors, preoperatively.

TL;DR: Postoperative choledochoscopic stone removal is safe and the method of choice for retained biliary tract calculi, while PTCS is highly indicated for those high-risk patients with or without previous biliary surgery.

TL;DR: In 18 patients who were treated with combined regional hyperthermia and radiation for recurrent pelvic tumors, blood flow related data were obtained using dynamic computed tomography and dynamic magnetic resonance imaging and significant differences in global perfusion have been observed.

TL;DR: It is concluded that MRI is a useful imaging diagnostic modality for evaluation of the anterior cruciate ligament deficient-knee and the intra-articular reconstruction of the ACL, thereby MRI affords the surgeon better preoperative planning.

TL;DR: Chemical shift imaging improves the understanding of the nature of the double-line sign of osteonecrosis and contributes to the appearance and location of the hyperintense line.

TL;DR: The new isotonic nonionic dimer iodixanol offers significantly better comfort to the patient than does ioxaglate, especially in relatively risky procedures that are unpleasant for the patients, such as conventional cerebral angiography.

TL;DR: Correlation with surgical findings was established in four patients, indicating that pseudoaneurysms complicating pancreatitis were not located within a pancreatic pseudocyst, and selective arteriography was superior to CT imaging in demonstrating pseudoaneuysm formation.

TL;DR: MR imaging of patients with muscle disease may contribute to the in vivo study of muscular dystrophy, its differential diagnosis and the detection of asymptomatic patients.

TL;DR: Follow-up CT from 4 to 30 months showed a progressive decrease in the size of adrenal glands from bilateral enlargement to small calcified glands and provides a clue to the etiology of Addison's disease and proper therapy.

TL;DR: MR fat suppression sequences showed to be as accurate as CT in detecting fat inside the cystic part of the teratomas and should be performed when presence of fat is suspected on images of ovarian tumors produced by standard MR sequences.

TL;DR: All three lymphomatous lesions appeared as unique well demarcated focal liver lesions on MR images, which were slightly heterogeneous and hyperintense to the liver.

TL;DR: It was demonstrated that magnetite as a contrast agent exhibited a much stronger relaxivity than gadolinium, and an alternative approach, using lymphocytes to be targeted to tumour cells, also proved feasible, in that these lymphocytes could be labelled with magnetite that had been incorporated into liposomes.

TL;DR: While CT showed a high level of failures, US appears to be an easy and helpful method for predicting non-invasion of the carotid wall and the usefulness of US in detecting invasion cannot be evaluated, due to the limited number of positive cases.

TL;DR: Only in one patient did electroencephalography (EEG) show typical triphasic sharp-waves, but this support to clinical diagnosis was obtained 1 month after the appearance of MRI alterations.

TL;DR: This is a book that will show you even new to old thing, and when you are really dying of whole body computed tomography, just pick this book; it will be right for you.

TL;DR: In communities where the traditional practice of infant feeding with ghee exists, these pulmonary radiological patterns, although in some cases indistinguishable from those of bacterial pneumoniae, should raise the suspicion of ghee administration with consequent early diagnosis and energetic management to avert prolonged morbidity and potential death.

TL;DR: Nine of the ten children evaluated by bronchograms performed during bronchoscopy had significant pathology demonstrated by the bronchogram that elucidated findings unclear from other imaging procedures at the time of bronchoscope.

TL;DR: Current imaging methods are insufficient for the accurate staging of gallbladder carcinoma, according to retrospectively analysis of radiological findings in 80 patients examined by US, CT and ERCP.

TL;DR: The relationship of the nodal stations to normal anatomy utilizing calcified nodes on CT scans is illustrated and the ease with which the map can be applied to cross-sectional anatomy is emphasized.

TL;DR: Eight patients with rectal carcinoid tumors were examined by endoscopic ultrasonography (EUS) to assess the depth of invasion of the rectal wall and four patients who were treated only with endoscopic polypectomy were completely cured.

TL;DR: FS-T1 was useful in evaluating vertebral metastases and showed various patterns, and SI measurement was not significantly different between the two groups.
