She had the typical findings of bilateral basal ganglion changes on MRI, as well as changes in the cerebellum and hippocampus. This case adds further information to the known imaging characteristics of CJD.

The diagnosis and differentiation in this instance were confirmed by MR angiography and a review of alternative imaging planes. A diagnosis of hypoglossal canal lesions should be made with caution, as these lesions are quite rare, and vascular anomalies, such as those described, may mimic disease in this region.

METHODS: One hundred twenty-five consecutive patients with possible acoustic schwannoma were examined. The accuracy of CISS-3DFT MR imaging in detecting abnormalities of the cerebellopontine angle, the internal auditory canal, and the inner ear was compared with T1-weighted contrast-enhanced spin-echo MR imaging by independent assessment of both image sets by two observers. RESULTS: The postcontrast T1weighted MR images revealed 18 cases of unilateral disease of the cerebellopontine angle and/or the internal auditory canal and no case of an abnormal bilateral cerebellopontine angle and/or internal auditory canal. Twelve cases were pathologically proved acoustic schwannomas. One meningioma of the cerebellopontine angle and one metastatic ependymoma to the cerebellopontine angle and the internal auditory canal was encountered. The four remaining cases had a provisional diagnosis of acoustic schwannoma and were scheduled for follow-up imaging and clinical review. Analysis of whether contrast material would have been administered to the appropriate patients (ie, those with disease of the cerebellopontine angle and/or internal auditory canal) according to CISS MR imaging findings revealed a sensitivity of 100% and a specificity of 98% for observer 1 and a sensitivity of 94% and a specificity of 94% for observer 2. CONCLUSION: CISS-3DFT MR imaging, in this patient population, provided high sensitivity and specificity in detecting lesions of the cerebellopontine angle and internal auditory canal; however, further experience is required before a definitive statement regarding the suitability of this technique as a screening procedure can be made. When contrast material cannot be administered, CISS MR imaging may be considered an adequate examination for the evaluation of possible acoustic schwannoma.

Diagnostic quality, 3 Mega Pixel, 21 inch monochrome LCD monitors -Planar C3i. 2. Clinical review quality, 2 Mega Pixel, 21 inch colour LCD monitors -Planar PX212. Two sets of seventy radiological studies were presented to four senior radiologists on two occasions, using different displays on each occasion. The clinical condition used for this investigation was to query for the presence of a solitary pulmonary nodule. Receiver Operating Characteristic (ROC) curves were constructed for diagnostic performance for each presentation. Areas under the ROC curves (AUC) for diagnosis using different monitors were compared and the following results obtained: Monochrome AUC = 0.813 +/-0.02, Colour AUC = 0.801 +/-0.021. These results indicate that there is no statistically significant difference in the performance of these monitor types at a 95% confidence level.

The course of the PIA is displayed by both conventional catheter angiography and by MR angiography (MRA). To our knowledge, neither an associated intracranial parenchymal AVM nor depiction of this congenital anomaly on MRA has been previously described. We also briefly review the embryology and anatomy of this anomaly.

At their dedicated cancer facility, the authors routinely perform a dynamic right anterior oblique first-pass study and a 4-minute left anterior oblique static planar study in addition to the routine equilibrium gated scanning in appropriate projections. Here they show the range of noncardiac disease encountered using this protocol. Useful unexpected information can be obtained from left ventricular ejection studies, and further data may be gained from these simple additions to this common test.

Five patients underwent intra-operative digital subtraction angiography (DSA) and carotid MRA within 5 days of carotid endarterectomy. An axial volume fast imaging in steady-state precession (FISP) gradient-echo 3DFT TOF carotid MRA technique in this limited series appeared to display accurately the surgically significant abnormalities at the carotid bifurcation after endarterectomy. However, in normal or near-normal intra-operative DSA studies, overestimation of internal carotid artery stenoses was encountered. Postoperative MRA demonstrates potential as a useful non-invasive investigation after carotid endarterectomy but should be interpreted with caution until larger studies become available.

The diagnosis was made on the basis of labeled red cell blood pool scintigraphy findings in conjunction with those of MR imaging. This lesion was not altered in appearance at 6-year follow-up MR imaging. We also present the labeled red cell blood pool scintigraphy findings obtained in three other patients with similar-appearing cavernous sinus lesions at MR imaging who underwent subsequent biopsy; histologic findings confirmed chondrosarcoma, chordoma, and meningioma, respectively.

Despite the prolonged history, discrete photopenia on the blood-pool phase and photopenia relative to the remainder of the ipsilateral carpus on the delayed phase of a bone scan in the region of the lunate was shown. When Kienböck's disease is seen in its late phase, the bone scan findings may be atypical in that they may not show the usual three-phase bone scintigraphic evidence of bone remodeling expected in delayed diagnosis avascular necrosis. A review of the previous literature is presented.

We performed this study to evaluate the year-by-year change in width and shape of the PMC in the young child. Materials and methods: We retrospectively reviewed temporal bone HRCT scans, performed between 2007 and 2012. Eighty children were included (age range: 0.3-6.9 years; median age: 3.1 years; 56% male). All scans had a slice thickness of 1 mm. Results: The average width of the PMC was 1.95 mm in children <2 years, compared to 0.83 mm in children !2 (p < 0.001). We categorized the PMC into 4 subtypes. A bulky (type III) PMC was predominant <2 years. A thin curvilinear (type I) PMC was more prevalent in the older children. Type II and IV PMC were found infrequently. The PMC width correlated inversely with the degree of pericapsular ossification (p < 0.001), and mastoid pneumatisation (p < 0.001). Conclusion: A wide PMC (!1 mm) is a common finding in children <2 years. As children grow older, the PMC progressively narrows. This correlates to increased temporal bone pneumatisation and ossification of the otic capsule. ß
