Facial asymmetry secondary to unilateral condylar hyperplasia can be a diagnostic challenge to oral and maxillofacial surgeons. Single positron emission computed tomography (SPECT) scans provide a useful adjunct. We report a brief summary of the evidence describing the effectiveness of different methods of analysing SPECT scans and compare it with the results of a 10-year study at Sunderland Royal Hospital. Overall, both the evidence base and our study strongly favour use of the condyle:condyle ratio over the condyle:reference bone ratio, suggesting that no further comparisons are needed.

Background: A patient presented to movement disorder clinic with cognitive complaints, imbalance and prior diagnosis of NPH. The patient underwent ventriculoperitoneal shunt in the past with minimal improvement, a detailed history is suggestive of REM sleep behavioral disorder, autonomic dysfunction including orthostatic hypotension and urinary incontinence.
Method: Clinical evaluation was notable for bradykinesia, rigidity, truncal and cervical dystonia, shuffling steps, reduced arm swing bilaterally and pink, dusky skin of both hands.

Approximately one-third of patients with focal epilepsy have medically refractory focal epilepsy (MRFE), which significantly impacts their quality of life. Once a seizure focus is identified and determined to be in the noneloquent cortex, it can be surgically resected with the goal of freedom from seizures and minimal neurocognitive deficit. During noninvasive (phase I) presurgical planning, functional (nuclear) imaging and structural imaging are complementary in the accurate localization of the epileptogenic zone (EZ).

Purpose: The aim of the study was to investigate the value of SwiftScan Step-and-Shoot Continuous (SSC) scanning mode in enhancing image quality and to explore appropriate scanning parameters for reducing scan time.
Methods: This study was composed of a phantom study and two clinical tests. The differences in visual image quality scores, coefficient of variance (COV) of the background, image signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and recovery coefficient (RC) of the sphere were compared between SSC mode and traditional Step-and-Shoot (SS) mode in the phantom study.

Objectives: This study aimed to evaluate the quality and associated quantitative values of bone single-photon emission computed tomography (SPECT) with and without SwiftScan using a semiconductor camera equipped with a cadmium-zinc-telluride detector.
Methods: Ten patients with bone metastases from prostate cancer who underwent list-mode SPECT/computed tomography using a whole-body semiconductor camera participated in this study. A total of 130 metastatic lesions from 10 patients were analyzed.

Objectives: Brain perfusion single-photon emission computed tomography (SPECT) image quality varies depending on SPECT systems. This study aimed to evaluate the relationship between physical parameters and visual analysis for assessment of the brain SPECT image quality. We conducted our phantom study under various conditions in a multi-center and multi-vendor study.
