Digital techniques are becoming well established as costeffective for vascular imaging in neuroradiology [1, 2]. Pediatric application of this technology is also under development [3]. Futhermore, there has been increasing use of more efficient, less invasive methods of evaluating pediatric spine problems through newer-generation computed tomography (CT), including scanned-projection radiograph...

ObjectiveTo evaluate and compare the radiographic efficacy and safety of a non-ionic dimeric and isotonic iodinated contrast medium, iodixanol (320 mgI/ml) and a non-ionic monomer and hypertonic contrast medium, iohexol (300 mgI/ml) in feline cervical myelography. DesignExperimental study AnimalsFive adult healthy cats. ProceduresIodixanol and iohexol were injected into the cerebellomedullary c...

BACKGROUND Spontaneous intracranial hypotension (SIH) due to cerebrospinal fluid (CSF) leakage at C1-2 poses diagnostic and therapeutic challenges to spine surgeons. Although computed tomography (CT) myelography has been the diagnostic imaging modality of choice for identifying the CSF leakage point, extradural CSF collection at C1-2 on conventional CT myelography or magnetic resonance imaging ...

Orthostatic headache is derived from low cerebrospinal fluid (CSF) pressure as evidenced by cranial magnetic resonance myelography (MRM). This reports three cases of patients coming with orthostatic headache without previous obvious spine trauma. The first two cases had headache with radiating neck pain while the third case had headache with radiating pain to the eye sockets or occasional nause...

The majority of cases of spontaneous intracranial hypotension (SIH) result from spontaneous cerebrospinal fluid (CSF) leaks. The disorder has a broad clinical and imaging spectrum, with substantial variability in clinical and imaging features, in CSF findings, and in response to treatment. Headache is the most common symptom, and is typically orthostatic, but with chronicity the orthostatic fea...

Neurologic signs and symptoms of brachial plexopathy may be subtle or confusing, making clinical localization of disease along the length of the brachial plexus difficult. To determine the most direct radiographic approach to diagnosing and anatomically delineating the cause of brachial plexopathy, we reviewed the clinical and radiographic records of 43 patients presenting with signs and sympto...
