These 30° in Schüller's view displaces the arcuate eminence of the petrous bone downward and shows the antrum and the upper part of the attic.
Schüller's view also gives an excellent view of the extent of the pneumatization of the mastoid,the distribution and the degree of aeration of the air cells, the status of the trabecular pattern, and the position of the vertical portion of the lateral sinus.
Anatomic snuffbox tenderness is a highly sensitive test for scaphoid fracture, whereas scaphoid compression pain and tenderness of the scaphoid tubercle tend to be more specific. Initial radiographs in patients suspected of having a scaphoid fracture should include anteroposterior, lateral, oblique, and scaphoid wrist views..........

Journal Effects of Dual-Energy Technique on Radiation Exposure and Image Quality in Pediatric Body CT.
AJR Am J Roentgenol. 2016 Aug 4:1-10. [Epub ahead of print]
Siegel MJ1, Curtis WA1, Ramirez-Giraldo JC2.
OBJECTIVE: The purpose of this study was to assess the effects of dual-energy CT (DECT) on radiation exposure and image quality in pediatric body CT.
MATERIALS AND METHODS: This retrospective study included 79 children (median age, 10.1 years; range, 12 days-18 years) who underwent thoracic or abdominal-pelvic CT or CT angiography with dual-energy technique between October 2014 and March 2015. The delivered volume CT dose index (CTDIvol) from DECT was recorded and compared with the estimated CTDIvol had the patient undergone scanning with a standard single-energy CT (SECT) protocol. Size-specific dose estimates were calculated for both DECT and SECT. Image quality was subjectively scored (scale, 1-4). For 16 of 79 patients who underwent both DECT and SECT, image contrast and noise were measured and contrast-to-noise ratio calculated. Parametric and nonparametric testing of independent and paired samples was performed.
RESULTS: For all 79 studies, actual median CTDIvol and size-specific dose estimate were 3.7 and 5.9 mGy for DECT versus prescanning estimates of 4.4 and 7.7 mGy for SECT, resulting in 12.5% and 11.2% radiation exposure reduction (p < 0.01). Diagnostic image quality was achieved in all patients. In the 16-patient subset, the median CTDIvol values of DECT and SECT were 3.1 and 3.4 mGy (p < 0.05). Median noise was greater with DECT than with SECT (p < 0.01), but the mean contrast-to-noise ratios for the liver and portal vein were similar (liver, p = 0.32; portal vein, p = 0.21).
CONCLUSION: In pediatric body CT, the use of DECT results in radiation exposures comparable to or less than those of SECT while maintaining contrast and contrast-to-noise ratio.

Most patients presenting with uncomplicated acute low back pain (LBP) and/or radiculopathy do not require imaging. Imaging is considered in those patients who have had up to 6 weeks of medical management and physical therapy that resulted in little or no improvement in their back pain. It is also considered for those patients presenting with red flags raising suspicion for serious underlying conditions, such as cauda equina syndrome, malignancy, fracture, and infection. Many imaging modalities are available to clinicians and radiologists for evaluating LBP. Application of these modalities depends largely on the working diagnosis, the urgency of the clinical problem, and comorbidities of the patient. When there is concern for fracture of the lumbar spine, multidetector CT is recommended. Those deemed to be interventional candidates, with LBP lasting for > 6 weeks having completed conservative management with persistent radiculopathic symptoms, may seek MRI. Patients with severe or progressive neurologic deficit on presentation and red flags should be evaluated with MRI.
The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer-reviewed journals and the application of well-established methodologies (the RAND/UCLA Appropriateness Method and the Grading of Recommendations Assessment, Development, and Evaluation) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Øas a complication of meningitis, paranasal sinusitis, otitis media, osteomyelitis, or a penetrating wound of the skull
Ø Frontal sinusitis is the most common cause
Ø Route: retrograde fashion through a dural sinus or through bridging veins
Ø even when small, usually cause focal neurologic deficits
Ø considered a neuro-surgical emergency because of its progressive clinical course.
ØDespite recent improvement in surgical technique and antibiotics, mortality remains high (25% to 40%).

Herpes simplex encephalitis
—most common endemic encephalitis in the USA (2 per million) and causes 10-20% of all viral encephalitis.
—Early diagnosis is important because AV therapy can decrease mortality and morbidity.
—HSV1 causes 95% of HSE. Most commonly occurs due to virus reactivation. HSV2 causes 80-90% of neonatal encephalitis

— Both HSV1 and 2 are commonly prevalent in Indian population. (Mixed=83%, HSV1=10%, HSV2=1%) 
— HSV2 along with TORCH agents are major causes of neonatal encephalitis.
— Infections result from maternal birth canal or transplacental spread
— Unlike HSV1, HSV2 infection in neonates is diffuse.
— Imaging findings are nonspecific.
— CT scans in early disease may be negative or show subtle areas of low density
— Conventional MR and DWI show lesions better.
— Lesions may be multifocal involving almost any area of brain or limited to temporal lobes brainstem and cerebellum.
— Watershed infarcts may be seen
— In-utero infections can result in microcephaly, encephalomalacia or calcification.
