A study for determination of various positioning errors in digital panoramic radiography for evaluation of diagnostic image quality.

Unlabelled: Faulty radiographs have poor diagnostic quality, and repetition of such poor-quality radiographs leads to increased patient exposure to radiation. Since digital panoramic radiography has replaced manual radiography, the only hindrance in producing good-quality radiographs is the positioning errors.

Objectives: Our study aims to determine the various positioning errors and their relative frequency and to identify those errors directly responsible for diagnostically inadequate images.

Current status and future trends in telepathology and digital pathology.

Objective: The purpose of this study was to assess the current status and future trends in telepathology (TP) and digital pathology (DP) in central India.

Materials And Methods: A self-constructed questionnaire including 12 questions was designed with five specialists, to improve the design ambiguity. The study was conducted through postal and online survey consisting of 12 questions and sent to 300 histopathologists.

Utility of lead thyroid collar in cephalometric radiography.

Objective: To investigate whether the application of thyroid collars (TCs) affects the results of cephalometric study.

Study Design: The Steiner cephalometric analysis of the patients was performed using lateral cephalometric radiographs, which were taken twice for each patient: Once using TCs (TC group; n = 50) and once without using TCs (NTC group; n = 50). A randomized and observer-blinded diagnostic study with head films taken from the two aforementioned groups was performed and results were evaluated with the t-test and Z-test, using GraphPad Prism 4 software.

Utility of digital volume tomography in maxillofacial trauma.

Purpose: To assess the diagnostic quality of images generated using the newly developed digital volume tomography (DVT) system and comparing them with conventional images from patients with maxillofacial trauma.

Materials And Methods: The study population included 22 male patients aged 18 to 60 years with a history of maxillofacial trauma. Each patient had undergone conventional radiographic and DVT examinations to analyze the number of fracture lines in the jaws and to compare the images for their diagnostic quality by an oral radiologist and a general radiologist using the χ(2) test.
