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 infertilityFemale 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 cavityHysterosalpingography 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 anatomyTransrectal 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 ExamsDiagnostic, 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 byteOur 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.

Small bowel findings reveal tumor spectrumThe 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).

Imaging modalities shed light on intracranial cystsAny 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.

PACS upgrades require careful advance planningA particular problem facing large teaching hospitals is that even as health information systems such as PACS and RIS require regular updating, the staff members using these systems are constantly changing. Interns and registrars will be moving through the hospital on fixed-term training placements. From a training point of view, the hospital IT support staff would prefer to have stable systems. This would allow training modules to be available online to a wide range of clinical staff who could learn the systems with a minimum of time, effort, and cost.
