Objective: To compare the helical and axial modes of indirect computed tomographic (CT) venography (CTV) for accuracy for diagnosing deep venous thrombosis (DVT) of the lower extremities as well as for their radiation burden in patients proven to have pulmonary thromboembolism (PTE) on CT pulmonary angiography (CTPA).

Subjects And Methods: Of patients evaluated with CTPA for suspected acute PE, 20 of patients who were found to have PTE underwent both indirect CTV of the lower extremities and color Doppler examination. For indirect CTV, patients were randomly assigned to helical and axial modes.

A 30-year-old man was admitted in PGIMER with the complaints of fever, altered sensorium and seizures. Magnetic resonance imaging (MRI) showed bilateral symmetrical temporal and frontal hyperintensities, which were highly suggestive of herpes simplex encephalitis. However, brain autopsy revealed it to be tuberculous meningo-encephalitis.

Objective: To analyse the spectrum of Takayasu's arteritis (TA) on multidetector CT angiography (MDCTA).

Materials And Methods: A retrospective analysis of the MDCTA findings was performed on 15 patients clinically diagnosed as Takayasu's arteritis. The spectrum and incidence of imaging findings on CTA were compared to studies in literature on catheter angiography in Takayasu's arteritis.

Background: The present study reports functional and morphological changes noted over long-term follow-up in patients with severe acute pancreatitis.

Methods: Thirty patients who had completed at least 6 months after recovery were included. Fecal fat, urinary D-xylose, blood sugar, C-peptide, pancreatic changes, and recurrences were studied.

Background: Hyperintense signals in the basal ganglia, namely the globus pallidus, have been reported on magnetic resonance imaging (MRI) in 70-100% of patients with cirrhosis of the liver. Deposition of paramagnetic substances, particularly manganese (Mn), has been reported to be responsible for these hyperintense signals. They are found in cirrhotics with or without overt/subclinical hepatic encephalopathy.

Objectives: To evaluate the role of dynamic magnetic resonance imaging (MRI) in craniovertebral junction (CVJ) abnormalities.

Materials And Methods: Twenty-five patients with suspected CVJ abnormalities underwent dynamic MRI of the CVJ, and in 20 of these patients, noncontrast computed tomography scan of the CVJ was done. The images were evaluated for atlantoaxial instability (AAI), spinal canal narrowing, cord compression, presence of altered cord signal intensity, and bony abnormalities in neutral, flexion, and extension.

Background: Computed tomographic colonography (CTC) is a new technique for detecting colonic neoplasms. Data on the utility of this method in the Indian population are limited.

Methods: Forty-two patients with symptoms of colonic disease underwent CTC and conventional colonoscopy (CC) within one week of each other and the findings at these two investigations were compared.

Objective: : To determine and compare the accuracy of contrast-enhanced magnetic resonance imaging (MRI) and Technetium 99m glucohepatonic acid single photon emission computed tomography (Tc-GHA SPECT) in grading of gliomas, compared with neuropathologic findings.

Materials And Methods: : The study included 20 adult patients (13 men and 7 women) with clinical/radiological suspicion of brain tumor (glial tumor) who were subjected to magnetic resonance examination and Tc-GHA brain SPECT.The lesions were evaluated by using MRI imaging score, based on 9 MRI criteria.

Objective: The purpose of our study was to determine the utility of dual-phase MDCT with 3D reconstruction in the staging and resectability of gallbladder carcinoma.

Subjects And Methods: Twenty-seven consecutive patients with suspected gallbladder carcinoma on clinical examination and routine sonography were prospectively analyzed with dual-phase MDCT. Of these patients, only 20 who underwent a laparotomy for extended cholecystectomy or a palliative surgery were included in the study.

Esophageal duplication cysts are rare congenital anomalies. These should be recognized as a cause of respiratory distress in infants and are usually associated with feeding difficulties. We report 2 such cases of esophageal duplication cyst in infants, causing acute respiratory distress.

Background: The purpose of the present study was to compare iissue harmonic imaging (THI) and conventional sonography in focal hepatic lesions.

Methods: Fifty patients with focal hepatic lesions were enrolled for study. Conventional grayscale and THI was performed in all the patients and two sets of images of the lesions were recorded (one each for THI and conventional) and assessed for fluid-solid differentiation, detail and overall image quality.

Fine-needle aspirationbiopsy (FNAB) is now widely accepted as a diagnostic modality for the treatment of hepatocellular carcinoma (HCC). The most common diagnostic problem in HCC is distinguishing it from a metastatic carcinoma. The literature from India on HCC is scanty.

The role of female sex hormones in the pathogenesis of gallstones is well established. Pregnancy, contraceptive use, estrogen replacement therapy in postmenopausal women, and estrogen therapy in men for the treatment of prostatic carcinoma have been found to be associated with increased risk of cholesterol gallstones. Alterations in gallbladder emptying and in bile lithogenicity in postmenopausal women receiving hormone replacement therapy (HRT) have not been studied to date.

To evaluate the role of tissue harmonic imaging (THI) in acute pancreatitis, and to compare its findings with conventional grey-scale sonography and contrast-enhanced computed tomography (CECT) scan, we evaluated 25 patients diagnosed with acute pancreatitis on clinical examination and laboratory findings. Conventional grey-scale ultrasound followed by tissue harmonic sonography was done on the same machine followed by a CECT within 12 h of the ultrasound examination. The present study showed that sonograms obtained with THI were of much better quality than those obtained conventionally, especially for the pancreatic tail.
