As stated by the editors in their preface, the authors tried to overcome the gap between reference books and up-to-date MRI applications, in order to provide the practicing radiologist with the appropriate tools to produce and accurately interpret excellent quality examinations in the setting of a busy daily routine. The competence of the authors in the MRI field is well known and documented in the recent literature, and the second edition of this book is awaited as a real quintessence of the clinically relevant information currently available in abdominal and pelvic MRI. ...

The common findings included a well-defined ovoid or rounded intraluminal mass; and uncommon findings included cavitation, diffuse thickening, or spiculation. Although CT manifestations of it are variable and nonspecific, a well-defined ovoid or lobulated intraluminal or lung peripheral mass with moderate to marked heterogeneous contrast enhancement may suggest the diagnosis of mucoepidermoid carcinoma of the lung. It should be included in the differential diagnosis of regional tumors.

Described is a schwannoma that developed as a pulmonary hilar nodule in a 38-year-old woman. The nodule showed strong 18F-fluorodeoxyglucose uptake with a maximum standard uptake value of 5.98 on positron emission tomography and had a high apparent diffusion coefficient (2.5×103 mm2/s) on diffusion-weighted magnetic resonance imaging. Combination of these functional imaging techniques warrants further evaluation in radiological diagnosis of intrapulmonary schwannoma.

Here, we report a case of a patient with melanoma causing complete atrioventricular block, which is a rare complication of this condition. The patient had multiple metastatic lesions from melanoma and had undergone multiple surgeries and later developed asystole which was treated with a pacemaker. Echocardiogram was performed but no metastatic lesion suggested or detected. Cardiac metastasis was not suspected until 5 months later when the patient underwent a FDG PET/CT for a whole-body evaluation which was interpreted to be suspicious for metastasis to the myocardium. This was confirmed by a repeat myocardial FDG PET scan. In this case report, the role of FDG PET in melano...

The study included 17 patients (28 pulmonary metastases) who underwent metastasectomy from CRC. The characteristic CT features include well-defined round or oval nodules in the peripheral or subpleural/fissural lung with frequent feeding vessel sign. The mean tumor volume doubling time was calculated as 160 days. With these growth rates, short-term follow-up (i.e., 5–6 months) would be helpful.

Although most malignant lesions involving the seminal vesicles are the result of secondary spread from other tumors, primary seminal vesicle carcinoma must be considered in the differential diagnosis, as the prognosis for this condition is dismal. Magnetic resonance imaging plays a crucial role in assessment, as it can exquisitely depict the anatomy of this region and define the extent of a seminal vesicle lesion.

The departmental error rate was 3.1%. Meaningful individual error rates could be determined in only the seven radiologists who interpreted ≥30 CT scans for acute appendicitis. Radiologic–pathologic correlation is an effective departmental monitor of interpretive accuracy, but individual accuracy can be assessed only for radiologists reading a large number of cases with pathologic proof.

Nasal meningoencephaloceles are uncommon anomalies and require a high index of suspicion for their diagnosis. Biopsy of such lesions without prior imaging studies can be detrimental because of the risk of cerebrospinal fluid leak and meningitis, and is therefore contraindicated. This case reiterates the fact that any child with an intranasal mass should undergo appropriate imaging studies prior to excisional biopsy.

We investigated the prevalence of sacroiliac joint vacuum phenomenon (SJVP) and the rate at which it is reported on abdominopelvic and lumbosacral spine computed tomography (CT) images by body imagers and neuroradiologists. We hypothesized that it would be more common than not and that neuroradiologists would identify it more frequently than body imagers and on spine images more commonly than abdominopelvic studies due to the search for the source of back pain in the former.Materials and methods: CT images of the pelvis and lumbar spine from January to February 2009 were retrospectively reviewed.

FDG-PET/CT showed uptake in the right side of the tongue, rendering this area a possible location for the primary tumor. However, clinical examination revealed a deviation of the tongue toward the left side indicating affection of the left hypoglossal nerve, causing the increased FDG uptake.This case illustrates the interpretive pitfalls of unspecific FDG uptake in PET/CT imaging of the head and neck.

Computed tomograph (CT) examination revealed a very large heterogeneously enhancing mass in the left kidney, measuring up to 28 cm. The mass was accompanied by several enlarged lymph nodes in the peri-aortic region. Radical nephrectomy was performed and pathologic evaluation revealed sheets of epithelioid cells and piecemeal necrosis consistent with malignant epithelioid angiomyolipoma (EAML) with regional lymph node metastases. The tumor cells were strongly positive for human melanosome-associated protein (HMB-45) on immunohistochemical staining. There was neither metastasis nor recurrence 2 years postoperatively. EAML is a rare tumor of mesenchymal tissue with potential for aggressive behavior. If ...

We used multimodal functional imaging technology to study a patient with marked neurological recovery after cranioplasty. Resting-state networks and auditory responses obtained with functional MRI and cerebral metabolism obtained with PET before and after cranioplasty revealed significant functional changes that were correlated with the subject's neurological recovery. Our results suggest a link between recovery of behavior, cerebral metabolism, and resting-state networks following cranioplasty.

Eighty-six patients with lung cancer were examined. A differentiation of non-small cell lung cancer vs. small cell lung cancer was possible with the parameters tumor necrosis, maximum contrast upslope, and the time until the maximum contrast upslope was reached. The beginning of a relevant contrast uptake, the mean time to peak and the time until the maximum contrast upslope was reached allowed a differentiation between squamous cell carcinoma and adenocarcinoma.

The 3-T fMRI shows a higher sensitivity for the motor and somatosensory stimulation and more specific localization in the grey substance. The 3-T fMRI detects additional areas of activation with the motor paradigm.

Being a well-known cause for developmental delay, mental retardation, and epilepsy, association of heterotopia with some other conditions has also been proposed. There are several case reports regarding the concurrence of heterotopia and encephalocele; however, no such association has been reported with cervical meningocele. Herein, we present the first case of periventricular nodular heterotopia associated with cervical meningocele. Our case further emphasizes the role of brain MRI in the evaluation of those with neural tube defects. Recognition of possible associated heterotopia is important for planning proper treatment and genetic counseling. (Source: Clinical Imagin...
