Olfactory Bulb Volume and Olfactory Sulcus Depth in

The olfactory sulcus can be readily visualized and manually measured using routine coronal MRI slices (Figure 2). Although not presented here, all automated measures for the olfactory sulcus were validated by manual sulcal depth measurements conducted by technicians who were blind to diagnosis, with inter-rater reliability (ICC) >0.90. Figure The olfactory nerve (CN I) is the first and most rostral of the cranial nerves . Along with the optic nerve, it is actually a peripheral outpost of the central nervous system. The bipolar cell is the first-order sensory neuron located in the roof of the nasal cavity, immediately inferior to the cribriform plate of the ethmoid bone Several studies have shown that patients with posttraumatic and postviral olfactory dysfunction as well as idiopathic olfactory loss have reduced OB sizes on MR images compared with healthy controls. 19 ⇓ -21 The depth of the olfactory sulcus, which is located between the gyrus rectus and medial orbital gyrus in the frontal lobe and. The current report used structural magnetic resonance imaging (MRI) to objectively measure olfactory bulb volume and olfactory sulcal depth in patients diagnosed with chronic schizophrenia and healthy controls. Additional measures were obtained to assess olfactory function. The olfactory bulb and sulcus were manually traced on structural 3T MRIs for 25 right-handed male patients diagnosed with.

  1. ations are often necessary, for example, for idiopathic smell disorders (Hoekman et al., 2014; Rudmik et al., 2014), for cerebral causes of smell disorders such as brain tumors, and, of course, for the evaluation of congenital anosmia with hypoplasia/aplasia of the olfactory bulb (OB), and a flattening of the olfactory sulcus (Abolmaali et al., 2002; Huart et al., 2011)
  2. ations of 88 normal fetuses between 24 and 39 weeks.
  3. The olfactory sulcus (OS) of the frontal lobe is visible above the OB and the olfactory tract (OT). The morphology of the OS seems dependent on the presence of the OB. The OT connects the OB with the perforate substance

Volumetric measurements of olfactory structures, the basal ganglia, and hippocampus were performed using magnetic resonance imaging (MRI). OB volume and OS depth were significantly reduced in PD patients compared to healthy control subjects (p<0.001 and p<0.001, respectively) To date, fetal MRI can depict olfactory sulci from 30 weeks gestational age onwards and olfactory bulbs from 30 to 34 weeks gestational age. This preliminary reference standard is useful to assess.. Olfactory bulb (OB) magnetic resonance imaging (MRI) is useful for evaluation of patients with anosmia/hyposmia as it allows for examination of the anatomic details, while T1-or T2-weighted images..

MATERIALS AND METHODS:In the current study, 200 patients who had cranial MRI were retrospectively evaluated

This magnetic resonance imaging (MRI) study investigated the olfactory sulcus morphology in BD patients and matched controls. Based on previous olfactory ability findings in BD and the potential role of olfactory sulcus depth as a marker of early neurodevelopment, we predicted a shallower olfactory sulcus in BD patients compared with controls Ultrasound images of the olfactory sulci were obtained in the anterior coronal plane of the frontal lobes, at the tip of the frontal horns of the lateral ventricle, which is the transfrontal plane according to guideline Clinical Study Olfactory Bulb Volume and Olfactory Sulcus Depth in Patients With OSA: An MRI Evaluation Adil Dog˘an, MD1, Nuray Bayar Muluk, MD2, and Hamza S¸ahin, MD3 Abstract Objectives: We evaluated olfactory functions in patients with obstructive sleep apnea (OSA) In the cranial MRI examination of all groups, the right, left and total olfactory bulb volume values were measured in mm 3, the right and left olfactory tract length values and the right and left olfactory sulcus depth values were calculated manually in mm. Demographic data including sex and age were recorded Abstract Olfactory deficit is known to occur frequently in Parkinson's disease (PD). This study aimed to explore olfactory deficit in PD and to investigate its possible correlation with the disease..

[MRI evaluation of the olfactory pathway

A hypoplastic olfactory sulcus was shown by MRI, but no olfactory bulb. The sulci measured were the olfactory sulcus (16 weeks), the parieto-occipital sulcus (22-23 weeks), the superior temporal sulcus (32 weeks) and the orbitofrontal sulcus (36-39 weeks). The olfactory bulb ends with the olfactory tract and is closely related to the olfactory. Background: There is limited knowledge of the MRI pattern of the development of fetal olfactory bulbs and sulci. Objective: To describe the MRI appearance of olfactory bulbs and sulci in normal in vivo fetuses according to gestational age

Among these subjects, the depth of the olfactory sulcus of 42 PD patients and 8 controls was measured in the plane of the posterior tangent through the eyeballs using the coronal view brain MRI. The CC‐SIT scores of the PD patients were significantly lower than those of the normal control (P < 0.001) MRI Atlas of the Brain.

netic resonance imaging, olfactory bulb, olfactory sulcus ABSTRACT We present a patient with congenital anosmia.The coronal T2-weighted magnetic resonance imaging (MRI) showed absence of the olfactory bulbs on both sides.We propose that conventional MRI may alert the clinician to the possibility of a congenital olfactory dysfunction. INTRODUCTIO Qualitative grading for olfactory bulb, olfactory tract, olfactory sulcus, subfrontal region, hippocampus, and temporal lobe damage also was performed. The absence of olfactory bulbs and tracts (68-84%) or the presence of hypoplasia (16-32%) was noted in all cases This sulcus, which resides in the basal forebrain directly overlying the olfactory tracts, is among the earliest to develop in utero and is identifiable in the fetal forebrain around week 16 of gestation. 81 The depth of the olfactory sulcus is a measure that appears to be directly linked to embryonic development of both the olfactory system and the cerebral cortex. It develops in association with the projection of the olfactory tract from the OB to the olfactory cortex and it appears to be. Methods We conducted a case-series on 10 consecutive COVID-19 patients who reported anosmia. Each patient prospectively underwent a validated olfactory test (Sniffin' Sticks test) and a brain MRI. Results Hypersignal intensity lesions of the central olfactory system were found in 3 subjects on 3D T2 FLAIR and 2D T2 High Resolution images with a lesion involving the olfactory bulbs and/or the. The right olfactory sulcus was completely absent in NAB-CA, trended toward shallower in NAB1(bulbarcontrol:mean=9.05±1.36mm,NAB1=6.37mm, two-tailed t(17) = 1.91, p = 0.07) but was typical in NAB2 (NAB2 = 9.6 mm, two-tailed t(17) = 0.41, p = 0.7) (Figure 1F). NAB-CA also had no apparent olfactory tracts, yet these were evident at T2 in NAB1 and NAB2
