Positron emission tomography (PET) using [(18)F]-2-deoxy-d-glucose (FDG) diagnoses, stages, and restages many cancers and is often better than anatomic imaging alone. However, abnormalities within the orbit present a challenge in evaluation, mainly due to the subtle findings on PET/computed tomography (CT). In addition, this region is typically at the edge of the field of view for the standard ...

BACKGROUND AND PURPOSE It has been shown that the brain of a preterm infant develops differently from that of a term infant, but little is known about the neonatal cerebrovascular anatomy. Our aims were to establish reference data for the prevalence of the anatomic variations of the neonatal circle of Willis (CoW) and to explore the effect of prematurity, MR imaging abnormality, vascular-relate...

objectives: this study aimed to evaluate the location and characteristics of mental foramen, anterior loop and mandibular incisive canal using cone beam computed tomography (cbct). materials and methods: this retrospective cross-sectional study evaluated 200 mandibular cbct scans for the location of mental foramen, anterior loop prevalence and mandibular incisive canal visibility, its mean leng...

skeletal abnormalities are most often used to describe defects in the arms or legs that are associated with genes or chromosomes, or that occur due to an event that happens during pregnancy. spider lamb syndrome (sls) is a congenital disorder in sheep breeding that is recognized by some deformities in skeletal system especially in the limbs.a dead day-old cross-breed white lamb with deformed li...

The use of cone beam CT (CBCT) is common among dentists and dental specialists in North America and the world. The regions of interest captured by these machines vary in size and applications are numerous. If using the image data from this modality, clinicians are obligated to examine the entire volume and to understand and recognize all the anatomy in the head and neck region that can be portr...

Pediatric trigger finger (PTF) is a rare hand disorder caused by various anatomic abnormalities and systemic illnesses. We report case of PTF in 16-month-old boy, revealing flexion deformity his right middle finger. noted an abnormally proximal location Camper’s chiasm bulging the flexor digitorum profundus intraoperatively. released A1 pulley completely resected ulnar slip superficialis (FDS)....

in this study, we demonstrate the appearance of anatomic defects of the uterine cavity on hsg after cesarian section. we define different shapes such as thin linear defect, focal saccular outpouching, unilateral or bilateral diverticula (dog-ear like) and fistula and different locations such as the uterine body, lower uterine segment, uterine isthmus and the upper endocervical canal. cesarean s...

Accurate recognition and reporting of spine abnormalities on MRI requires knowledge of normal anatomy and its variants. This article deals with common normal variants, points out pitfalls which may be sources of errors in interpretation and describes imaging artifacts which are essential to be recognized and not mistaken for true pathologies.
