Primary malignant melanoma of uterine cervix is extremely rare malignancy with very few case published reports. This neoplasm is having poor prognosis, so early diagnosis, staging and treatment is of extreme importance. 18F-FDG PET-CT (18F-labeled fluoro-2-deoxyglucose positron emission computed tomography) scan is an established modality to determine exact extent of disea...

Background: In recent years, neoadjuvant chemoradiation and subsequent surgical resection with total mesorectal excision has been shown to increase local control with decreased toxicity. Neoadjuvant chemoradiotherapy is the standard treatment for locally advanced rectal cancer. In this study we evaluated the efficacy a cox-2 inhibitor on pathologic response, sphincter preservation and acute tox...

errors and variations in interpretation can happen in clinical imaging. few studies have examined the biased effect of clinical information on reporting of brain ct scans. in a blinded double crossover design, we studied whether three radiologists were biased by clinical information when making ct scan diagnosis of the brain. three consultant radiologists in three rounds with at least a one-mon...

Correctly staging lung cancer is extremely important because the treatment options and the prognosis differ significantly by stage. Several noninvasive imaging studies are available to aid in identifying disease both within and outside of the chest. Chest CT scanning is useful in providing anatomic detail that better identifies the location of the tumor, its proximity to local structures, and w...

OBJECTIVE To assess the value of positron emission tomography (PET) compared with computed tomography (CT) in the initial staging of esophageal cancer. DESIGN Case series. SETTING Tertiary care veterans hospital. PATIENTS Patients with newly diagnosed esophageal cancers from January 1996 through May 2001 who underwent both CT and PET scanning within 4 weeks were included in the study (n =...

Neuroblastoma is the third most common malignancy of childhood. Nowadays, MIBG has become a central procedure for staging and defining extent and location of neuroblastoma tumors. The recommendations of the International Neuroblastoma Staging System (INSS) indicate that MIBG scintigraphy must be performed in patients with neuroblastoma at the time of initial staging and as a followup tool durin...

BACKGROUND Among patients with early-stage non-small cell lung cancer (NSCLC), preoperative imaging tests are important in defining surgical candidates. OBJECTIVE To assess whether whole-body positron emission tomography and computed tomography (PET-CT) plus cranial imaging correctly upstages cancer in more patients with NSCLC than does conventional staging plus cranial imaging. DESIGN Rand...

Lung cancer presents a high prevalence around the world and constitutes the leading cause of death due to cancer in men and women. Proper staging is essential in order to provide the correct treatment and estimate survival. PET/CT imaging is the method of choice for the staging of lung cancer patients with a better performance than the traditional imaging methods. It allows defining the primary...

BACKGROUND Positron emission tomography (PET) scanning is used increasingly to detect and stage lung cancer, but the test performance characteristics and relationship of PET to patient outcomes remain undefined. OBJECTIVE To determine the test performance characteristics and relationship of PET scanning stage to patient outcomes relative to the 1997 International System for the Staging of Lun...
