Aim:We aimed to reveal the facet joint orientation and tropism and their relationship with age in patients without degenerative spine disease in lumbar magnetic resonance imaging (MRI) examinations.Methods:After obtaining approval from the ethics committee, patients who were referred to our clinic for a lumbar MRI between June 2018 and December 2018 for low back pain were reviewed retrospectively. When the line that is tangent to the posterior of the intervertebral disc was considered as reference, tropism was considered when the difference between the anteromedial and posterolateral line of superior articular facet on the right and left sides, and the angles between this reference lines were >10°.Results:The study included 113 patients aged 15-55 years (30.87±9.23) who underwent lumbar MRI for various reasons and with reports of normal lumbar MRI examination. Sixty-seven-point three percent (n=76) of the patients were female and 32.7% (n=37) were male.Conclusion:According to the results of our study, facet joint orientation has increased angular values in the craniocaudal direction regardless of age, and it shows more coronal orientation compared to other levels, especially at the L4-5 and L5-S1 levels. We may conclude that facet tropism is independent of age and is an acquired condition which degenerative processes may contribute to.

Background/Aim: Although normal Color Doppler US (CDU) findings of the carotid system were described by many studies, normal findings of the vertebral system have not been studied extensively. This study aimed to evaluate vertebral artery CDU hemodynamic and morphologic findings in patients with normal vertebral arteries (VAs) on 64-slice Computed Tomography Angiography (CTA) and investigate the correlation between RDUS and CTA in evaluating the VA anatomy.Methods: In this retrospective cohort analysis, the patients referred to our radiology department for CTA who had normal VA anatomy underwent a CDU for visualization of the orifice and segments (V1-V2) of the VA. Peak systolic velocity (PSV), and end-diastolic velocity (EDV) were measured in V1 while PSV, EDV were measured and resistive index and FV were calculated in V2. The presence of hypoplasia and dominance were noted.Results: A total of 77 patients who had normal vertebral arteries on CTA were included in this study. CDU findings were highly consistent with multislice CTA findings regarding the measurement of VA diameter (ICC=0.856, ICC=0.830), hypoplasia (kappa=0.488), and dominance (kappa=0.752). No consistency was found between the two modalities in the visualization of the orifice and V1 segment of the VAs on both sides. CTA was able to show the orifice and the V1 segment in all cases, while the success rate was lower in CDU, especially in terms of visualizing the orifice of VA. VA FV was not significantly different between the patients with and without vertebrobasilar insufficiency (P=0.300). Conclusion: CDU findings were consistent with 64-slice CTA findings in VA diameter measurement and the diagnosis of hypoplasia and dominance. However, CTA is more successful than RDUS in evaluating the vertebral artery orifice and V1 segment, the most common sites of atherosclerotic involvement. There was no significant difference between the patients with and without VBI symptoms in evaluating FV.

Spontaneous intracranial hypotension (SIH) is a condition in which the fluid pressure inside the skull is lower than normal. It is secondary to cerebrospinal fluid (CSF) leak at the level of the spine and the resulting loss of CSF volume. Pseudo-subarachnoidal hemorrhage is a rare condition that can occur in patients with spontaneous intracranial hypotension. The diagnosis is very important because it can be confused with true subarachnoidal hemorrhage. True subarachnoidal hemorrhage is one of the complications that may occur in SIH patients. The differentiation of these two conditions as well as computed tomography (CT) and magnetic resonance imaging (MRI) findings and the response of the blood-patch treatment applied by interventional radiology is also very valuable., Spontan intrakraniyal hipotansiyon (SIH), kafatasının içindeki sıvı basıncının normalden düşük olduğu bir durumdur. Omurga seviyesinde beyin omurilik sıvısı (BOS) sızıntısına ve bunun sonucunda BOS hacim kaybına sekonder gelişir. Psödo-subaraknoidal kanama, spontan intrakraniyal hipotansiyonu olan hastalarda görülebilen nadir bir durumdur. Tanı çok önemlidir çünkü gerçek subaraknoidal kanama ile karıştırılabilir. Gerçek subaraknoidal kanama SIH hastalarında ortaya çıkabilecek komplikasyonlardan biridir. Bu iki durum arasındaki farkın bilgisayarlı tomografi (BT) ve manyetik rezonans görüntüleme (MRG) bulguları ve girişimsel radyoloji tarafından uygulanan kan-yama tedavisinin yanıtı çok değerlidir.
