CT and MRI give answers in cardiac neoplasms

Noninvasive cardiac imaging is gaining widespread acceptance. Both CT and MRI can determine the absence or presence of coronary artery disease accurately and reliably. This is done by either assessing the coronary artery morphology or by offering detailed insight into functional aspects and myocardial perfusion.

No premedication equals fewer staff, more patients

Coronary CT angiography is commonly performed using beta blockers to slow the heart rate and reduce motion artifacts in the images, thereby improving diagnostic accuracy. Oral metoprolol is often prescribed one hour prior to the procedure. Intravenous metoprolol may be given immediately prior to the procedure as an alternative or if oral beta blocker alone did not achieve adequate heart rate control.

Small bowel findings reveal tumor spectrum

The spectrum of usual and unusual primary neoplasms involving the duodenum, jejunum, and ileum is extremely wide. Our own database of digestive pathology contains a range of benign small bowel neoplasms (adenoma, leiomyoma, lipoma, familial polyposis, hemangioma, lymphangioma, and fibroma), as well as examples of malignancy (adenocarcinoma, carcinoid tumor, lymphoma, leiomyosarcoma, direct extension from extraintestinal tumors, and metastasic lesions).

No More Déjà Vu - Improving Your Practice in 2011

We must accept: 1) the assertion that market and political forces are designed to lower our incomes and profits; and 2) it is our responsibility to innovate and act proactively to manage change. With this acceptance we can actually improve our income and profits rather than sitting on the sidelines as a helpless non-participant. Please join us this year with this mind set as our focus.

Speech Recognition Technology - Finally Ready for Prime Time?

With the release of the iPhone 4S and Siri, Apple has introduced speech recognition (SR) technology to the masses. Apple bills and markets Siri as a “humble personal assistant.” However, I doubt many radiologists, who have been working with SR technology for multiple years, would describe their SR software systems this way.

Static and cine imaging offers clues to female infertility

Female infertility accounts for two-thirds of all infertility problems, and it can be due to tubal, ovarian, and/or uterine factors. Tuboperitoneal disease is thought to be a contributing factor to infertility for up to 40% of infertile couples.

Indian radiology meeting scores a hit with first-time attendee: ‘a small-scale RSNA’

Despite obtaining my basic radiology residency training in New Delhi, I had never attended any of the Indian radiology meetings. When I was invited as a speaker, I was keen on using this opportunity to experience radiology in the Indian setting.

Imaging keeps major role in uterine cavity

Hysterosalpingography is the radiographic evaluation of the uterine cavity and fallopian tubes after injection of radiopaque contrast through the cervical canal. The first hysterosalpingography, performed in 1910, was considered to be the first interventional radiological procedure.

Transrectal sonography clearly visualizes prostate anatomy

Transrectal ultrasound provides clear images of the prostatic anatomy and accurate guidance for prostate biopsy.1 The technique has become useful for the evaluation of patients with prostatic disease, but its success depends greatly on individual operators. It is important for radiology staff to understand the correct approach to prostate scanning and biopsy procedures, as well as the indications and limitations.

Improved Evaluation and Follow-up of Routine Diagnostic Oncology Exams

Diagnostic, staging and follow-up exams for tumors are among the most frequent CT exams performed in many radiology departments. For the University of Erlangen, oncology related imaging represents approximately 60% of the daily CT workload. To date, exams are read and evaluated in 2D, employing manual measurement and reporting of lesions.

PACS images can be treated byte by byte

Our PACS project at the University Hospitals Leuven in Belgium radically follows from an overall IT perspective. The emphasis on image flow throughout the entire hospital supersedes operations within the image-generating departments. Image management outside the radiology department is not an afterthought, but rather an integral part in, and even a driving factor for, decisions that the department makes. Although images have specific characteristics and requirements, we often consider them yet another type of data or a collection of bytes.

Imaging modalities shed light on intracranial cysts

Any fluid-filled cavity or sac that is lined by an epithelium is a cyst, and intracranial cystic lesions are a common finding on CT and MR imaging of the brain.1,2 These lesions contain either cerebrospinal fluid, fluid that is similar to CSF, mucus, or proteinaceous fluid. They are lined by epithelial cells, inflammatory cells, or glial cells. The attenuation characteristics of the cyst on CT and MRI and the contrast enhancement patterns depend on the cyst's contents and the composition of the wall.
