Imaging of rectal cancer.
Abstract International guidelines dictate that magnetic resonance imaging (MRI) should be part of the primary standard work up of patients with rectal cancer because MRI can accurately identify the main risk factors for local recurrence and stratify patients into a differentiated treatment. The role of endoscopic ultrasound (EUS) is restricted to staging of superficial tumors because EUS is able to differentiate between T1 and T2 rectal cancer. Recent guidelines recommend the addition of diffusion-weighted (DWI) MRI to clinical and endoscopic assessment of response to preoperative radiochemotherapy (RCT). MRI...

[Pulmonary carcinoids and carcinoids of the small intestine].
Abstract CLINICAL/METHODICAL ISSUE: Pulmonary carcinoids and carcinoids of the small intestine (jejunum and ileum) are often asymptomatic and can affect various parts of the body, which makes diagnosis difficult. STANDARD RADIOLOGICAL METHODS: Contrast-enhanced computed tomography (CE-CT) is commonly used for primary diagnostics. In case of concomitant pulmonary consolidation (e.g., atelectasis or pneumonia), tumor lesions can be obscured. In addition, differentiation between atypical (AC) and typical carcinoids (TC) is not possible using CT. Small tumors of the small intestine are easily overlooked (sensitiv...

Abstract Starting with the smallest functional unit, the spinal segment including the centrally located intervertebral disc, the spine and pelvis including the sacroiliac and hip joints form a functional unit. The discs play an important role in the complex interaction between disc, osseous and ligamentous structures and the adjacent muscles. Disc pathologies are very frequently associated with changes of the adjacent endplates of the vertebral bodies and can be depicted at an early stage using magnetic resonance imaging (MRI). The focus of the diagnostics and assessment of degenerative disc pathologies shoul...

Abstract CLINICAL/METHODICAL ISSUE: Colorectal cancer is one of the most common malignant tumors. Preoperative imaging is crucial in rectal cancer as patients can only receive optimal treatment when accurate staging is performed. The N‑staging is often difficult with the available options and must be called into question as a staging parameter.

Abstract CONTEXT: Although in recent times more research has been done on interactions of metallic dental objects in magnetic resonance imaging (MRI), radiologists are often uncertain whether the objects should be removed or can be retained prior to an impending examination. On the one hand, they want to avoid unnecessary material removal which is associated with costs and potential damage of the dental object. On the other hand, they fear material-induced susceptibility artefacts will impair the diagnostic workup so that examinations will have to be repeated. The lack of information complicates adequate decision ...

Abstract BACKGROUND: Hybrid imaging FDG PET/CT (18F‑fluordeoxyglucose positron emission tomography/computed tomography) has gained increasing importance in oncology in recent years. DIAGNOSIS: A focal increase in FDG uptake in the gastrointestinal tract may be due to colorectal carcinoma. Such a finding requires further clarification. PRIMARY STAGING: Staging of the primary and locoregional lymph nodes remains a domain of established imaging modalities as FDG PET/CT does not provide a clear additional benefit. Liver metastases can be detected with high sensitivity by FDG PET/CT, but...

Abstract Preoperative radiological diagnostics in patients with colorectal cancer has several objectives. The diagnostic localization of the colonic tumor is essential for planning the resection. The radiologically suspected infiltration of neighboring structures may lead to the decision for neoadjuvant treatment. In patients with rectal carcinomas, the T and N stages, the distance to the circumference resection margin (CRM), and the penetration of the tumor into the mesentery must be determined. This crucial to determine whether the patient should undergo neoadjuvant treatment. Prior to the planned relocatio...

Imaging plays a pivotal role in screening family members and in diagnosis. DIAGNOSTIC METHODS: Diagnosis is based on ultrasound (US), thyroid scintigraphy, serum calcitonin and carcinoembryonic antigen (CEA) as well as fine needle biopsy. High-resolution US is the most important imaging method for locoregional staging, combined with computed tomography (CT) of the mediastinum. Positron emission tomography (PET...

Abstract Image guidance has been playing a decisive role throughout the history of radiotherapy, but developments in 3D-and 4D imaging data acquisition using computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET) have significantly boosted the precision of conformal radiotherapy. An overarching aim of radiotherapy is conforming the treatment dose to the tumor in order to optimally limit a high radiation dose outside the target. Stereotactic, intensity modulated, and adaptive radiotherapy are all largely based on appropriately using imaging information both befo...

Besides pathognomonic hormonal findings, PC/PGL can exhibit typical imaging features. However, PC/PGL can also show morphological overlap with other pathologies. STANDARD RADIOLOGICAL METHODS: The modality of choice for evaluation of PC is CT. In case of extra-adrenal location, MRI is superior to CT. Imaging with PET-CT provides complementary information in the differentiation of PC/PGL and is recommended as the i...

Abstract Subchondral osteonecrosis of large weight-bearing joints (hip and knee joints) represents a severe and joint-threatening disease. Apart from idiopathic forms, glucocorticoid medication and alcohol abuse have been identified as major causative factors for atraumatic osteonecrosis. In addition to direct cytotoxic factors, a critically reduced perfusion of the subchondral osseous space will eventually lead to bone marrow ischemia and osseous necrosis.

Abstract Diffusion-weighted imaging enables us to detect acute ischemic stroke early and with high sensitivity and specificity. Its signal changes are based on decreased diffusion of water molecules that is caused by cytotoxic edema. Several different neurological diseases can also cause restricted diffusion and therefore mimic stroke. These can generally be reliably distinguished from ischemic stroke based on location, morphology and signal behavior in other magnetic resonance imaging sequences.
