Image fusion of SPECT and PET data with CT and MRI has been shown to improve diagnostic accuracy in a variety of clinical circumstances. While the use of SPECT/CT and PET/CT image fusion has been well documented in the literature, there has been limited documentation of the role of planar image fusion. This brief pictorial review provides case examples where planar fusion between bone scintigraphy and xray has been useful.

Color Doppler twinkling artifact has been described in stones of urinary and biliary tract, parenchymal calcifications, medical materials such as encrusted ureteral stent, intracerebral coil. To the best of our knowledge this artifact has not been published in sludge of gallbladder before. This artifact is concerned to the strongly reflective structure and sonography machine settings. Twinkling artifact mimics a real blood flow in color mode Doppler examination and it may lead to wrong diagnosis. We present a case of twinkling artifact related to the sludge of gallbladder that might represent a trap in color Doppler imaging in the differential diagnosis of gallbladder tumor.

Each year over two hundred thousand women in the United States will be diagnosed with breast cancer. In most cases, the entire experience is both frightening and stressful. After a breast biopsy, for some, the news brings a big sigh of relief when they hear that wonderful word benign. For others, the words ‘you have breast cancer’ will forever change their lives. From that moment on, they will either be battling breast cancer or a breast cancer survivor. Along the road to survival the patient will have to make many important decisions some of which will ultimately affect their prognosis. Treatment options can be overwhelming when your life literally depends on the choices made. One hundred women were asked if diagnosed with invasive breast cancer would their treatment choice be mastectomy or lumpectomy and radiation. The vast majority of those polled chose mastectomy when scientific studies have shown the survival rate is the same when comparing mastectomy with lumpectomy and radiation. The purpose of this article is to remind healthcare professionals the decisions made by women regarding breast cancer treatment can be very emotional, confusing and difficult.

We describe a novel presentation of cerebral amyloidosis. The strongly enhancing appearance of this deep white matter mass with large ‘stippled’ hematoma in a young patient has not been previously described. Our case serves to highlight the varied imaging appearance of cerebral amyloidosis, as well as the therapeutic dilemma. CAA should be considered when faced with the presentation of an unusual hematoma or enhancing mass.

AIM: To evaluate the normal liver volume in north Indian population by using spiral computerized tomography. METHODS: CT data of 337 patients (176 males, 161 females) was prospectively evaluated. Body parameters (body height, body weight, body surface area and body mass index) and laboratory data were collected. After data processing, the volume of liver was assessed. RESULTS: The mean liver volume was found to be 1445.20 ± 329.18 cm3. Liver volume best correlated with age (p < 0.05, correlation coefficient: r = 0.13) and correlation with body height was 0.10 and with other parameter as body weight, BMI and BSA was respectively (p < 0.05) 0.05, 0.08 and 0.09. CONCLUSION: The Liver volume assessed with computerized tomography scanning has correlated well with age reciprocally and with body height positively.

Purpose : To compare clinical diagnosis established by Physical examination with High frequency ultrasonographic findings in patients with painful shoulder. Methods & Materials: two different Radiologists who were blinded to the clinical data, performed sonographic examination on forty patients with painful shoulder and twenty control subjects using 7.5 MHZ linear transducer. Physical examination was performed by one experienced Rheumatologistbefore ultrasonographic examination by using specific maneuvers. Ultrasonography was considered the optimal diagnostic technique. Results : Rotator Cuff was most common structure to show abnormalities on ultrasound. Among the tendon of rotator cuff supraspinatus most commonly showed abnormalities (52.5%). Partial thickness tears of supraspinatus were more common than full-thickness tear. A high Sensitivity and Specificity of sonography was demonstrated compared to physical examination in the present study. Conclusion : High sensitivity & specificity , non-invasiveness & low cost of high resolution sonography justify its routine utilization for the assessment of painful shoulder.

There are various types of surgeries performed on the lungs, airways, pleura, and chest wall. As radiologists, it is imperative to understand the various surgeries, their expected post-operative imaging appearance and possible complications. The thoracic surgeries are broadly divided into two categories: open surgery and minimally invasive surgery. This article is a multi-modality review of open and minimally-invasive surgeries performed on the lung, pleura, trachea and chest wall. Computed tomography (CT) images, positron emission tomography (PET) images and radiographs, as well as intra-operative photographs and original illustrations of surgeries are provided to enhance understanding.

Idiopathic thrombocytopenic purpura, an immune-mediated disease, usually has a relatively benign clinical course. Bleeding manifestations are mostly mucocutaneous and mild. Massive hemorrhage requiring transfusions or other interventions are rare, unless platelet counts are extremely low or other complicating conditions coexist. We describe a 24year old woman, case of chronic ITP presenting with severe abdominal pain prompting an urgent Ultrasound and MR examination which showed ovarian torsion with ruptured ovarian hemorrhage causing massive hemoperitoneum. The specific sign of torsion is demonstration of multiple follicles of uniform size (8-12 mm in diameter) in the cortical peripheral portion of a unilaterally enlarged ovary. MR imaging showed enlarged ovary with peripherally situated T2 hyperintense follicles and ruptured ovarian capsule with better demonstration of pedicle. Large amount of subacute blood noted in peritoneal cavity suggested by hyperintensity on both T1 and T2.

E. granulosus is one of the most important helminthic pulmonary diseases and human echinococcosis is still a significant clinical problem more so in endemic areas. Hydatid cysts of the lung are often indistinguishable from a variety of other pulmonary lesions such as lung tumors. Also, pulmonary hydatid cysts are usually solitary.We present an unusual case of a 23 year old man with chest pain and dyspnea who presented with bilateral pulmonary nodules on chest radiograph due to echinococcosis that mimicked pulmonary metastases. The diagnosis of hydatidosis was suggested on CT scan which demonstrated multiple thin walled pulmonary cystic lesions and involvement of liver and spleen as well with similar lesions.During the evaluation of the bilateral multiple pulmonary masses on chest radiograph pulmonary echinococcosis must be kept in mind as a possible differential diagnosis, more so in endemic areas. CT is very helpful to characterize these types of lesions which shows their cystic nature and involvement of other body organs.

Aim: To evaluate the initial experience with the first double independent reading at screening mammography in JamaicaMethod: This was a retrospective review of all patients presenting to the Breast Imaging Unit for Screening Mammography at the University Hospital of the West Indies from October 2006 to April 2007Results: A total of 368 women were screened. Of these, 101 were undergoing their first screening mammogram. 77 had done one previous mammogram. 190 women had done more than 2 mammograms. The age of the women screened ranged from 36 to 90 years of age. The mean age was 55 years. 36 women were considered abnormal. 36 women were considered abnormal. Suspicious microcalcification was the most common abnormality reported. No malignancies were confirmed at histopathological evaluation.Conclusion: The recall rate in our study was very low. No cancers were detected. This is likely due to the small sample size. Detection rates are not likely to improve unless more eligible women participate in breast cancer screening in Jamaica.
