Comparison of Accuracy of Conventional Periapical Radiography and Direct Digital Subtractions Radiography with or without Image Enhancement in the Diagnosis of Density Changes

Journal of Dental Research, Dental Clinics, Dental Prospects, 2012
Background and aims. In periapical radiographic technique, the changes will be visible only after considerable deposition or resorption while digital subtraction technique visualizes slight density changes. This study was aimed to compare visualization

Subtraction Technique in Intravenous Aortography

Radiology, 1977
Excretory urography using the subtraction technique (100 ml of 60% urographic media injected in 10-12 seconds) demonstrated the aorta and its major branches well enough to prove useful clinically. The method is fast and graphic, and risk seems no greater than that associated with the standard urographic examination.

Resonance-aware subtraction in the dipole method

European Physical Journal C: Particles and Fields, 2019
We present a technique for infrared subtraction in next-to-leading order QCD calculations that preserves the virtuality of resonant propagators. The approach is based on the pseudo-dipole subtraction method proposed by Catani and Seymour in the context ...

High-Stringency Subtraction for the Identification of Differentially Regulated cDNA Clones

BioTechniques, 1997
The technique of high-stringency subtraction described here facilitates subtractive hybridizations between directional cDNA libraries constructed in λ ZAP® II cloning vectors and represents an improvement on earlier methods for the subtraction of entire ...

Additive role of dynamic subtraction MRI in assessment of unresolved HCC post-radiofrequency ablation

The Egyptian Journal of Radiology and Nuclear Medicine, 2021
Background Malignant Hepatocellular carcinoma (HCC) is one amongst the foremost widespread cancers within the world. Radiofrequency ablation (RFA) is that the most generally used substitute tool for hepatic carcinoma treatment.

Subtraction MRI versus diffusion weighted imaging: Which is more accurate in assessment of hepatocellular carcinoma after Trans Arterial Chemoembolization (TACE)?

The Egyptian Journal of Radiology and Nuclear Medicine, 2016
This study aims to compare the role of both subtraction MRI and Diffusion weighted images in assessment of HCC after trans-arterial chemo embolization (TACE). Patients and methods: 32 patients having 54 HCC lesions underwent TACE.

Dynamic ARMA-Based Background Subtraction for Moving Objects Detection

IEEE Access, 2019
Background subtraction is a prevailing method for moving object detection in videos with stationary backgrounds. However, accurate and real-time moving object detection is challenging in the presence of complex dynamic scenes. This paper presents a novel
