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).

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.

PACS upgrades require careful advance planning

A 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.

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.

Enterprise-wide 3D assists radiology/surgery workflow

It is becoming increasingly important in modern distributed healthcare enterprises to view and manipulate 3D images. CT and MRI systems are creating ever larger volumes of data. This has increased the need for fast and efficient 3D postprocessing tools, such as multiplanar reconstruction, volume rendering, curved reformatting, and volume measurement.

Comment: The ECR – a mirror reflecting my life as a radiologist

The first ECR meeting that I attended was in 1999. I had started a CT practice in a hospital in Mumbai in 1995 with a conventional CT scanner and when it was time to upgrade to a spiral CT scanner, my wife and I thought it would be a good idea to attend an international conference. After our experience at the RSNA in Chicago in 1994, which had left us with severe sensory and physical overload from running from one place to another, trying to attend everything at once, a smaller meeting seemed more appealing.

MSCT venography finds cerebral thromboses

Dural sinus and cerebral venous thromboses (CVT) are difficult to diagnose. Symptoms are often nonspecific and may evolve slowly, and anatomic variations can further complicate diagnostic decision making. Unilateral aplasias of the transverse or sigmoid sinus, frontal agenesis of the superior sagittal sinus, and high partitions of the transverse sinus are common pitfalls in the diagnosis of CVT.

CT angiography data offernew approach to perfusion

40-slice scanners boost neuro CT angiography

The introduction of 40-slice CT scanners has opened up new possibilities for CT angiography of the supra-aortal vasculature. Imaging can be performed with even thinner slices, and more rapidly, than on 16-slice systems, and images have higher resolution. Conventional protocols for imaging the brain and its arterial supply must be adjusted to profit from these parameters.

MRS gains indications, but still fights for reimbursement

To paraphrase Mark Twain, reports of the death of diagnostic MR spectroscopy are greatly exaggerated. CPT 76390 is considered standard of care as an effective imaging technique for the diagnosis, treatment, and monitoring of patients with brain lesions by Cigna Healthcare, a respected healthcare provider,1 though declared "investigational" by Blue Shield, Anthem, and Medicare. Radiologists and other physicians are confused and annoyed by some insurers' refusal to reimburse for their MRS services.
