Brief Summary
The adjustment of radiation dose in many CT protocol are based on body mass index(BMI) or weight of the patient. In the literature, neck circumference (NC) has been reported as a new anthropometric parameter indicating the body mass for the upper body. NC may be an important landmark in the determination of the low dose protocols for upper body CT examinations such as neck, chest and coronary CT.

Outcome Measures
Primary Outcomes (1)
The measurement of neck circumference of the patients undergoing non-enhanced thorax CT
Before CT examination, during patient preparation, neck circumference was measured horizontally at the level of the cyricoid cartilage by a non-elastic flexible tape (centimeter, cm)
1 year
Secondary Outcomes (3)
The measurement of weight of the patients undergoing non-enhanced thorax CT
1 year
The measurement of height of the patients undergoing non-enhanced thorax CT
1 year
Calculating the body mass index (BMI) using the results of each patient measured in outcome 2 and outcome 3.
1 year
Study Arms (1)
The patients underwent thorax CT
OTHERThe patients refered to radiology service underwent thorax computed tomography without contrast material for the evaluation of various complaints such as dyspnea, hemoptysis and pulmonary infections.
