Possible role of endocannabinoids in olfactory and taste dysfunctions in Alzheimer's and Parkinson's patients and volumetric changes in the brain.

The purpose of this study is to determine the volumes of primary brain regions associated with smell and taste in Alzheimer's and Parkinson's patients and healthy controls using MR imaging and examine volumetric changes in comparison to smell/taste questionnaire and test results and endocannabinoid (EC) levels. The study included 15 AD patients with mild cognitive dysfunction scored as 18 ≤ MMSE ≤ 23, 15 PD patients with scores of 18 < MoCA < 26 and 18 ≤ MMSE ≤ 23, and 15 healthy controls. A taste and smell questionnaire was given to the participants, and their taste and smell statuses were examined using the Sniffin' Sticks smell identification test and Burghart Taste Strips.

Evaluation of dural venous sinuses and confluence of sinuses via MRI venography: anatomy, anatomic variations, and the classification of variations.

Purpose: We aimed to determine the anatomical variations more comprehensively particularly at the level of superior sagittal sinus (SSS), confluence of sinuses (CS), transverse sinuses (TS), straight sinuses (SS) and occipital sinuses (OS) with the help of the images obtained via MRI venography, and to contribute to the classification efforts.

Methods: In our retrospective study, we evaluated 211 patients who admitted to our hospital with various complaints and cerebral MRI venography has been performed. All investigations were performed by using 1.

Antronasal Polyp Extending to Orbital Fossa.

Sinonasal infections and nasal polyps can be taken as 2 components of a disease. Polyps due to chronic inflammations of nasal cavity and sinuses are not rare. They may present with various clinical signs and symptoms, while the secondary complications may cause serious problems.

Radiological Imaging of Rare Intracranial Complications Secondary to Otitis Media and Mastoiditis.

Acute otitis media used to cause fatal results because of its intracranial complications before the introduction of potent and effective antibiotics. After the introduction of antibiotics, complications have started to be observed more frequently as a result of chronic otitis media and especially in children. Because clinical findings changed and became indistinct, the diagnosis of otitis and mastoiditis has been made occasionally with imaging findings only after complications occurred.

Congenital abnormalities of the ribs: evaluation with multidetector computed tomography.

Objective: To evaluate congenital abnormalities of ribs using multidetector computed tomography.

Methods: The retrospective study was conducted at Mustafa Kemal University Research Hospital, Hatay, Turkey and comprised data of patients aged 1-45 years who attended the Radiology Department for computed tomography of the thorax between January 2010 and July 2013. Multiplanar reconstructions, maximum intensity projections, and 3-dimensional images were acquired to investigate numerical and structural abnormalities of the ribs of the patients who underwent multidetector computed tomography for a variety of indications.
