"In our opinion, in the evaluation of patients with suspected metastases, a hepatic ultrasound exam must be performed only after contrast administration," said Dr. Vito Cantisani, a radiologist at the University of Rome La Sapienza. Researchers put low mechanical index (MI) real-time CEUS, conventional B-mode ultrasound, and 64-slice CT to the hepatic detection test on 88 patients with suspecte...

Background: Prospectively electrocardiography (ECG)-triggered high-pitch spiral coronary computed tomography angiography (CCTA) is a unique scan mode for dual-source CT (DSCT). Our reports aim to compare image quality and radiation dose of CCTA using high-pitch spiral or sequential acquisition mode in patients with low and stable heart rates. Materials and Methods: Patients with low and stable ...

background: conventional tomography used for evaluation of the small areas of the jaws provides acceptable information. it has some advantages of availability, less radiation dose and costin comparison to computed tomography (ct) and cone beam ct. double emulsion film usuallyused for taking tomograms requires less exposure than single emulsion film; on the other hand,the latter provides more sh...

A 39 year old man presents with a swelling in his neck that has been progressively enlarging over the last few months. 1. What clinical tests would you perform to assess him? 2. The swelling moves upwards when the tongue is protruded. What is the likely cause, and how common is this condition? 3. Describe the embryological origin of the thyroid and its significance in this case. A representativ...

Recently, investigators have begun evaluating the ability of spiral computed tomography (sequence scan mode-SEQ) to measure coronary calcium. Electron Beam Tomography (EBT) and SEQ studies were performed in 10 women and 23 men, with a mean age of 54+/-9 years. The EBT study was performed within 4 weeks (mean 11+/-4 days) of the SEQ with no clinical interval event (MI, revascularization). The me...
