The purpose of this study is to identify the landmarks and associated radiation dose reduction for limited CT of the kidneys of patients requiring follow-up for known nephrolithiasis.
This article was published in the following journal.

The purpose of this work is to demonstrate quantitatively the complementary relation between the introduction of intensity-modulated radiation therapy (IMRT) and planning target volume (PTV) margin re...
Interventional radiology is a rapidly evolving speciality with potential to deliver high patient radiation doses, as a result high standards of radiation safety practice are imperative. IR radiation s...
We hypothesized that unenhanced brain MRI can be used in follow up of patients with intracranial meningioma to avoid gadolinium deposition in the brain and allow measurement of meningioma dimensions f...
Videofluoroscopic swallowing studies expose both the patients and the staff to ionising radiation. Although the radiation exposure is considered low compared to other diagnostic procedures, it is stil...
We evaluated the efficacy of low-dose (LD) radiation (≤7.5 frames/second [f/s]) compared with standard-dose (SD) radiation (≥10 f/s) in cardiac catheterization (CC) and percutaneous coronary inter...
Pain in the right lower abdomen is one of the commonest reasons patients present to general surgeons as an emergency. Whether or not such patients have appendicitis is crucial to their ass...
This study is designed to find the optimum radiation dose and number of cycles for an ABVD chemotherapy combined with an involved field irradiation. It is to be tested whether the reductio...
Computed Tomography (CT) is widely used in abdominal imaging for a variety of indications. Contrast media (CM) is used to enhance vascular structures and organ parenchyma. Attenuation of t...
The purpose of this study is to assess new low radiation dose techniques for clinical PET/CT scans through intra-individual comparison between a clinical, standard dose scan and a low-dose...
Hypothesis: Does a 50% reduction in radiation in dose significantly affect the diagnostic quality of chest CT
Administration of the total dose of radiation (RADIATION DOSAGE) in parts, at timed intervals.
The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.
The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).
The relationship between the dose of administered radiation and the response of the organism or tissue to the radiation.
A treatment schedule in which the total dose of radiation is divided into large doses.
