INTRODUCTION The medial maxillary sinus roof is a ridge formed by the superior margin of the maxillary sinus antrostomy. The posterior wall of the maxillary sinus is always included in operative fields. OBJECTIVE To perform a radiologic study assessing the utility of the medial maxillary sinus roof and the posterior wall of the maxillary sinus as fixed landmarks for providing a safe route of ...

A case of duplication of the patella in the coronal plane is reported. Previously reported cases of double patella have shown sagittal or vertical duplication, and some have been associated with multiple epiphyseal dysplasia. In our case, excision of one patella and realignment of the extensor mechanism relieved symptoms of giving-way.

BACKGROUND AND PURPOSE Second harmonic imaging (SHI) is a novel ultrasound technique that allows the evaluation of brain tissue perfusion. The purpose of this study was to assess normal cerebral echo contrast characteristics in 3 regions of interest (ROIs) in the transverse axial and coronal insonation planes through the temporal bone window. Materials and Methods- SHI examinations were perform...

light of recommendations of ACR. STUDY DESIGN Aclinical audit. PLACE AND DURATION OF STUDY Department of Radiology, Jinnah Hospital, Lahore, from August 2015 to February 2016. METHODOLOGY Scans of 20 patients who underwent MRI of knee in August 2015 were studied retrospectively to assess the quality of images obtained in the first audit. Based on the findings of this audit, recommendation...

PURPOSE We devised an intraoperatively identifiable mechanical axis (IIMA) as a reference of alignment in total knee arthroplasty (TKA). MATERIALS AND METHODS Between February 2010 and January 2011, primary TKAs were consecutively performed on 672 patients (1007 knees) using an IIMA as a reference in the coronal plane. RESULTS The alignment of the lower extremity improved from a mean of 11....

BACKGROUND AND PURPOSE Routine axial CT images may not be ideally suited for detecting ICH in transversely oriented locations such as the floor of the anterior and middle cranial fossas and vertex. This study was performed to evaluate whether coronal reformations improve detection of ICH in NCCT performed for head trauma. MATERIALS AND METHODS All patients undergoing a first NCCT in the ED fo...

Unicondylar fractures of the femur that occur in the coronal plane (Hoffa fractures) are uncommon and most often affect the lateral condyle. Conservative treatment generally yields poor results, but rigid internal fixation allows early functional rehabilitation and decreases the incidence of malunion, nonunion, and stability loss. This case report describes open reduction and internal fixation ...

Intraoperative identification of small or diffusely infiltrative subcortical lesions may be difficult. The apparent position of an abnormality demonstrated on higher CT sections may be particularly misleading. Lesions seen in the center of the image may be located in the frontal or parietal lobes, depending on the angulation of the plane of the section. Surgical exploration of these lesions is ...

This study aimed to compare two-dimensional (2D) and three-dimensional (3D) methods for evaluating implant alignment in navigated UKA. Nineteen UKAs in 18 subjects (7 men) were performed using an image-free navigation system. Coronal and sagittal implant alignments were assessed using radiographs (2D evaluation) and 3D image-matching software. The accuracy of 2D evaluation was compared with tha...
