Background and objectives: The advent of high-resolution MRI with a dedicated epilepsy protocol improves the ability to identify possible structural abnormalities that underlie seizure disorders. The aims of this study were to evaluate the diagnostic
efficacy of standard MRI, identify whether there is an increase in the diagnostic yield with the addition of dedicated seizure protocol, and compare the diagnostic yields of MRI and electroencephalogram (EEG) individually and in combination. Subjects and Methods: This was a cross-sectional analytic study, included 100 cases who presented with seizure over 18 months. Patients underwent complete neurological examination, EEG, and MRI with a standard and dedicated epilepsy protocol. Results: We found epileptogenic lesions in MRI in 55.5. Mesial temporal lobe sclerosis was the most common epileptogenic lesion (45.5%). The diagnostic efficacy of MRI had increased with dedicated epilepsy protocol compared to standard protocol. Abnormal MRI and EEG were compatible in 21%. Conclusion and implications: Dedicated epilepsy protocol increased the diagnostic efficacy of brain MRI in detecting a structural epileptogenic lesion, with 100% of mesial temporal sclerosis, the most common lesion in our study, was detected only in dedicated epilepsy protocol and missed in standard protocol.
Renal artery stenosis is an important clinical entity. its
importance lies in that it may be a treatable cause of
hypertension, and it is -when progress- a cause of chronic
renal failure. The causes of renal artery stenosis are
numerous, the most
common are: atherosclerosis and
fibromuscular dysplasia (accounts for more than 95% of
cases). Digital Subtraction Angiography (DSA) is the standard
reference in the radiologic diagnosis of renal artery stenosis,
but it carries the risk of being invasive procedure. Doppler
ultrasound is used in the evaluation of the renal arteries, and
it has the advantage of being non-invasive and inexpensive.
